mono/mcs/class/System.XML/System.Xml.Schema/ChangeLog

2004-09-16  Atsushi Enomoto <[email protected]>

	* BuiltInDatatype.cs, SchemaDataValueType.cs :
	  ParseValue() for xs:AnyURI should return System.Uri. MS.NET returns
	  XmlSchemaUri, but it is derived from System.Uri, while ours was not.

2004-09-07  Atsushi Enomoto <[email protected]>

	* IXmlType.cs : deprecated in .NET 2.0.

2004-09-03  Atsushi Enomoto <[email protected]>

	* XmlSchema.cs : When schema inclusion results in a recursion, just
	  skip recursed schema.
	* BUGS-MS.txt : added another entry. Reflected response from Microsoft.

2004-08-30  Atsushi Enomoto <[email protected]>

	* XmlSchemaType.cs : quick build fix.

2004-08-30  Atsushi Enomoto <[email protected]>

	* XmlSchemaDatatype.cs : Removed FromName(localName) that cannot
	  handle xdt:* types.
	* XmlSchemaType.cs : added internal GetBuiltInType() methods that
	  mix GetBuiltInSimpleType() and GetBuiltInComplexType().

2004-08-25  Atsushi Enomoto <[email protected]>

	* XmlSchemaSimpleType.cs : Fill list types such as xs:IDREFS.
	* XmlSchemaType.cs :
	  Fixed TypeCode more (broken on predefined list types and xs:anyType).

2004-08-25  Atsushi Enomoto <[email protected]>

	* XmlSchemaType.cs :
	  anyType was anonymous, thus GetBuiltInComplexType() didn't work.

2004-08-24  Atsushi Enomoto <[email protected]>

	* XmlSchemaType.cs : return XmlTypeCode.AnyAtomicType for
	  anySimpleType's TypeCode property.

2004-08-10  Atsushi Enomoto <[email protected]>

	* XmlSchema.cs : Replace XmlSchemaCollection with XmlSchemaSet that
	  used to maintain compiled schema state.
	  Simplified code a bit (Include processing).
	  Set IsCompiled = true only when successfully compiled.
	* XmlSchemaCollection.cs : Now it totally delegates its processing
	  to XmlSchemaSet. Removed unused methods.
	* XmlSchemaElement.cs : Added post-compiled information initializer
	  method, and call it before (re)Compile().
	* XmlSchemaSet.cs :
	  - Replaced internal store from Dictionary to List, since schema
	    resources for one target namespace can be more than one (that's why
	  - Schemas(string targetNamespace) returns ICollection).
	  - Now global schemaset members are added per schema addition (it is
	    more MS compatible than before).
	  - Use GetSafeNs() to do targetNamespace comparison correctly.

	  XmlSchemaSet looks still unstable, so it will be changed again.

	* XmlSchemaSimpleTypeRestriction.cs,
	  XmlSchemaSimpleTypeUnion.cs,
	* XmlSchemaUtil.cs : Consider xdt namespace.

2004-08-10  Atsushi Enomoto <[email protected]>

	* XmlSchemaCollection.cs : replaced CRLF to LF (they were mixed).

2004-08-10  Atsushi Enomoto <[email protected]>

	* XmlSchema.cs : code reformatting. convert CRLF to LF.
	  Use String.Format() instead of +. Removed commented code.

2004-07-28  Atsushi Enomoto <[email protected]>

	* BuiltInDatatype.cs : use XmlQualifiedName.Parse().

2004-07-23  Atsushi Enomoto <[email protected]>

	* XmlSchema.cs : Added internal XdtNamespace constant. don't fill
	  schemaset compoenents here.
	* XmlSchemaAttribute.cs : Implemented AttributeSchemaType.
	* XmlSchemaElement.cs : Implemented ElementSchemaType.
	* XmlSchemaSimpleType.cs : Added predefined simple types
	* XmlSchemaType.cs : Implemented GetBuiltInSimpleType().
	* XmlSchemaDatatype.cs : Allow Xdt namespaces too (not completed;
	  quick fix for GetBuiltInSimpleType()).

2004-07-21  Atsushi Enomoto <[email protected]>

	* BUGS-MS.txt : updated including answer excerpts from MS team.
	* BUGS.txt : it turned out that some bugs I wrote as "MS bugs" are 
	  actually my bug. Noted them.
	* BuiltInDatatype.cs :
	  Commented out extraneous [CLSCompliant].
	  Switch ParseValue() argument as IXmlNamespaceResolver for 2.0, and
	  XmlNamespaceManager for 1.x.
	  Added TypeCode overrides.
	* XmlSchemaDatatype.cs : Added 2.0 members.
	  Switch IXmlNamespaceResolver and XmlNamespaceManager.
	* XmlSchemaType.cs : Added some NET_2_0 members. removed old 1.2 stuff.

2004-07-13  Atsushi Enomoto <[email protected]>

	* XmlSchemaBuiltInType.cs, XmlSchemaValidity.cs, XmlTypeCode.cs
	  : fixed annoying enum errors.
	* XmlSchemaCollection.cs : completely delegate to XmlSchemaSet.
	* XmlSchemaSet.cs : sealed classes. Use ListDictionary (avoid annoying
	  order preservation matter). NameTable null check for .ctor().
	  Fill GlobalAttributes, GlobalElements, GlobalTypes correctly.
	  Add(string, XmlReader) checks namespace conflicts, while
	  Add(XmlSchema) does not. Fixed Schemas() return type.

2004-07-11  Atsushi Enomoto <[email protected]>

	* XmlSchemaDatatypeVariety.cs : Fixed class name typo.
	* XmlValueConverter.cs : fixed return types.

2004-06-18  Atsushi Enomoto <[email protected]>

	* CustomSerializer.cs, XmlSchemaException.cs,
	  XmlSchemaParticle.cs, XmlSchemaSimpleTypeRestriction.cs
	  : Globalization.

2004-06-10  Atsushi Enomoto <[email protected]>

	* XmlSchemaFacet.cs : Fixed internal protected --> internal.

2004-06-06  Atsushi Enomoto <[email protected]>

	* XmlSchema.cs : Make sure to close url-based XmlTextReader.

2004-06-03  Atsushi Enomoto <[email protected]>

	* BuiltInDatatype.cs,
	  XmlSchemaFacet.cs,
	  XmlSchemaSimpleTypeRestriction.cs,
	  XmlSchemaXPath.cs : modified some enum const to static readonly
	  (.NET 1.0 does not allow it). Use safe overload of LookupNamespace().

2004-05-22  Atsushi Enomoto <[email protected]>

	* XmlSchemaDatatypeVariety.cs,
	  XmlSchemaValidity.cs : they are NET_2_0 enums.

2004-05-22  Atsushi Enomoto <[email protected]>

	* XmlValueConverter.cs : missed NET_2_0.

2004-05-22  Atsushi Enomoto <[email protected]>

	* IXmlSchemaInfo.cs,
	  IXmlType.cs,
	  XmlSchemaDatatypeVariety.cs,
	  XmlSchemaValidity.cs,
	  XmlTypeCode.cs,
	  XmlValueConverter.cs : added.

	* XmlSchemaInfo.cs : removed (.NET 1.2).

	* XmlSchemaBuiltInType.cs,
	  XmlSchemaSet.cs : updated.

2004-05-19  Atsushi Enomoto <[email protected]>

	* CustomSerializer.cs : Added custom serializer for XmlSchema, that is
	  generated by SerializationCodeGenerator and edited a bit.
	* XmlSchema.cs : Use XmlSchemaSerializationWriter.

2004-05-13  Atsushi Enomoto <[email protected]>

	* XmlSchema.cs : Removed FIXME. No PSVI required.
	* XmlSchemaAll.cs : Removed FIXME. It was not done.
	* XmlSchemaAttributeGroupRef.cs : Removed FIXME. It can be annotated.
	* XmlSchemaChoice.cs : not FIXME but LAMESPEC.
	* XmlSchemaSimpleTypeRestriction.cs : Added check for non 
	  XmlSchemaFacet items on Compile(). Thus removed FIXME.
	* XmlSchemaUtil.cs : Fixed SplitList to handle sequential spaces.
	  Thus removed FIXME.
	* XmlSchemaObjectTable. cs: modified to use HybridDictionary (mostly
	  for avoiding iterator order difference).

2004-05-13  Atsushi Enomoto <[email protected]>

	* XmlSchemaSimpleTypeRestriction.cs : Removed MonoTODO. done.

2004-05-12  Atsushi Enomoto <[email protected]>

	* BuiltInDatatype.cs : made classes/enums internal.

2004-05-05  Atsushi Enomoto <[email protected]>

	* BuiltInDatatype.cs : trivia fix

2004-05-05  Atsushi Enomoto <[email protected]>

	* BuiltInDatatype.cs : added BUGGY_MS_COMPLIANT condition and that
	  handles ms-compatible properties.
	* XmlSchemaComplexType.cs : ditto for ContentTypeParticle of xs:anyType.
	  Make sure ContentType for xs:anyType is Mixed.
	* XmlSchemaUtil.cs : ditto for <xs:attribute use="prohibited" ..>

2004-05-05  Atsushi Enomoto <[email protected]>

	* XmlSchema.cs : Write() handles schema namespace for xmlserializer
	  (it does not look to be handled inside xmlserializer).

2004-04-27  Atsushi Enomoto <[email protected]>

	* XmlSchemaComplexType.cs : Set basetype as ur-type for such complex
	  type that has an immediate Particle (W3C specified as restriction
	  of ur-type).

2004-04-27  Atsushi Enomoto <[email protected]>

	* XmlSchemaAttribute.cs : When type was inline simple type, it is not
	  validated correctly.
	* XmlSchemaSimpleType.cs : When Content was restriction, DataType was
	  not indicating base type's Datatype correctly.

2004-04-06  Atsushi Enomoto <[email protected]>

	* XmlSchemaDatatype.cs : optimized Normalize() not to create
	  extraneous string objects.

2004-03-15  Atsushi Enomoto <[email protected]>

	* reverted the latest XmlSchemaUnique.cs change (MS.NET looks fine to
	  reject incorrect schemas ;-)

2004-03-04  Alon Gazit <[email protected]>

	* XmlSchemaUnique.cs : Changed Read implementation.
	Currently can read "field" element before "selector" element (like MS).  

2004-02-26  Atsushi Enomoto <[email protected]>

	* XmlSchemaCollection.cs : Implemented SyncRoot and IsSynchronized
	  (as always synchronized).

2004-02-16  Atsushi Enomoto <[email protected]>

	* XmlSchema.cs,
	  XmlSchemaAttribute.cs
	  XmlSchemaAttributeGroup.cs,
	  XmlSchemaComplexContent.cs,
	  XmlSchemaComplexType.cs,
	  XmlSchemaContent.cs,
	  XmlSchemaDatatype.cs,
	  XmlSchemaNotation.cs,
	  XmlSchemaObject.cs,
	  XmlSchemaParticle.cs : extra TODO removal. foreach elimination.
	    Moved attribute group recursion check field from XmlSchemaObject 
	    to XmlSchemaAttributeGroup.
	    Fixed XmlSchemaParticle.EmptyParticle class access modifier.
	* XmlSchemaSimpleType.cs,
	  XmlSchemaSimpleTypeContent.cs,
	  XmlSchemaSimpleTypeList.cs,
	  XmlSchemaSimpleTypeRestriction.cs,
	  XmlSchemaSimpleTypeUnion.cs : Removed "actualBaseSchemaType" field
	    and the owner simpleType should hold the corresponding type info.
	    Collect base type info in prior to validation.

2004-02-05  Atsushi Enomoto <[email protected]>

	* BUGS-MS.txt : fixed incorrect thought on case 008. Added case 014.
	* BUGS.txt : FYI.

2004-02-03  Atsushi Enomoto <[email protected]>

	* BuiltInDatatype.cs : Fixed some Parse() for token based datatypes.
	* XmlSchemaAny.cs : set properties for cloned particle. This will fix
	  bugzilla #53668.
	* XmlSchemaParticle.cs : copy occurence string after computation of
	  validated min/max occurence. This will fix bug #53667.

2004-01-26  Atsushi Enomoto <[email protected]>

	* XmlSchema.cs : Raise warning event when external schema could not 
	  be resolved.
	* XmlSchemaAll.cs : Fixed incorrect IsEmptiable computation.
	* XmlSchemaAny.cs : Fixed incorrect occurence computation.
	* XmlSchemaChoice.cs : compiledItems were incorrectly appended.
	* XmlSchemaComplexType.cs : Now validatableParticle became extraneous.
	* XmlSchemaGroupBase.cs : Here we should not get optimized particle
	  because it might cause infinite loop.
	* XmlSchemaGroupRef.cs : Fixed Validate() to avoid null reference 
	  exception (only occur with ValidationEventHandler).  Fixed Occurence
	  embedding logic that was useless because of particle optimization.

2004-01-22  Atsushi Enomoto <[email protected]>

	* BuiltInDatatype.cs : On parsing QName, we don't have to spend costs
	  on Add()ing parsed name to name table.
	* XmlSchemaUtil.cs : Added IsBuiltInDatatypeName().
	* XmlSchemaAttribute.cs, XmlSchemaComplexType.cs, 
	  XmlSchemaElement.cs, XmlSchemaSimpleContentExtension.cs,
	  XmlSchemaSimpleContentRestriction.cs, XmlSchemaSimpleTypeList.cs :
	  Use the method above instead of Namespace string comparison.
	  (it will be required to validate schema for schemas.)
	* XmlSchemaComplexType.cs : Type Derivation OK (3.4.6) should also
	  treat null base type as anyType.  Derivation Valid Restriction 
	  (3.4.6) should allow base type wildcard absense in case of anyType.

2004-01-22  Atsushi Enomoto <[email protected]>

	* XmlSchema.cs : When we have schema A which includes schema B which
	  includes schema C (i.e. A->B->C), C components should be compiled.
	  Here, same URL inclusions are ignored.
	* XmlSchemaElement.cs : Hack for missing substitution-group fix.
	* XmlSchemaSimpleTypeContent.cs : make actualBaseSchemaType private
	  and initialize. This fixes bug #53178.
	* XmlSchemaSimpleTypeUnion.cs : Forgot to commit ;)

2004-01-22  Atsushi Enomoto <[email protected]>

	* XmlSchemaSimpleTypeRestriction.cs : regexp improvements. Modify
	  pattern string as "^str$" and convert WXS specific char classes into
	  .NET regexp patterns.

2004-01-21  Atsushi Enomoto <[email protected]>

	* XmlSchema.cs :
	  - Removed extra property Language.  Fill substitution-group info
	    before ContentTypeParticle is computed.
	* XmlSchemaComplexType.cs : ContentType and ContentTypeParticle are 
	  now computer before Validate() (to exclude 3.4.2 from 3.4.6
	  component constraint check).
	* XmlSchemaObject.cs, XmlSchemaParticle.cs :
	  Added CopyInfo() for cloning objects.
	* XmlSchemaObjectTable.cs :
	  Add() doesn't have to reject same named items.
	* XmlSchemaParticle.cs :
	  - Renamed internal class XmlSchemaParticleEmpty to EmptyParticle 
	    (for ease of post compilation infoset comparison).
	  - GetMinEffectiveTotalRange() should return max occurs for element and
	    any.
	* XmlSchemaParticle.cs,
	  XmlSchemaAll.cs,
	  XmlSchemaAny.cs,
	  XmlSchemaChoice.cs,
	  XmlSchemaElement.cs,
	  XmlSchemaGroupBase.cs,
	  XmlSchemaGroupRef.cs,
	  XmlSchemaSequence.cs :
	  - Removed ActualParticle property.
	  - Added GetOptimizedParticle() to get ContentTypeParticle.
	  - ContentTypeParticle is now created as different object from 
	    user-specified "Particle" property.
	  - Return Empty particle when model groups contains no Items.
	  - When Items contains exactly 1 item, return the item (unless it is
	    top level choice model group - it causes DBR problem).
	  - ValidateDerivationValidRestriction() and related WXS 3.9.6 DBR
	    check methods such as ValidateNSRecurseCheckCardinality() now
	    returns a bool value and avoids exceptions on each failure time.
	  - ValidateRecurse() now doesn't progress base particle incorrectly.
	    (it caused incorrect order-preserving-mapping error.)
	  - 3.9.6 Recurse, RecurseLax, MapAndSum are now treated as different.
	* XmlSchemaAll.cs : occurence validation shoud be done against values
	  after computation (ValidatedMaxOccurs).
	* XmlSchemaChoice.cs : When Items is empty, then invoke warning event.
	* XmlSchemaElement.cs :
	  - Consider referencedElement also for SubstitutionGroupElement.  
	  - Removed SubstitutingChoice which is not in use.
	  - when it was targeted as substitution group by other elements, its 
	    ContentTypeParticle should be substitution choice (see 3.9.6 
	    Particle Valid (Restriction) term 2.1).
	  - Added FillsubstitutionElementInfo() (see XmlSchema.cs above).
	* XmlSchemaGroup.cs : Removed extra check on model group (because it
	  is impossible to specify non-model-group particle).
	* XmlSchemaIdentityConstraint.cs,
	  XmlSchemaKey.cs,
	  XmlSchemaKeyRef.cs,
	  XmlSchemaUnique.cs : Removed extraneous MonoTODO.
	* XmlSchemaSimpleContent.cs : Made actualSchemaType as internal.
	* XmlSchemaSimpleType.cs : Removed extraneous new Datatype property.
	* XmlSchemaSimpleTypeRestriction.cs : Renamed actualBaseSchemaType to
	  ActualBaseSchemaType.
	* XmlSchemaSimpleTypeList.cs, XmlSchemaSimpleTypeUnion.cs :
	  Removed unused actualBaseSchemaType code.
	* XmlSchemaType.cs : use recently introduced BaseXmlSchemaType.
	* XmlSchemaUtil.cs : Removed unused CheckLanguage().

2004-01-21  Atsushi Enomoto <[email protected]>

	* XmlSchemaXPath.cs : wildcard with prefix (e.g. @foo:*) was
	  incorrectly treated.

2004-01-20  Atsushi Enomoto <[email protected]>

	* SchemaDataValueType.cs : UriValueType.ToString() should return 
	  actual URI string (as MS's XmlSchemaUri class does).
	* XmlSchemaReader.cs : Make it internal.

2004-01-16  David Sheldon <[email protected]>

       * BuiltInDatatype.cs: added guard to stop index out of range error for
         invalid Base64 characters.

2004-01-15  Jackson Harper <[email protected]>

	* XmlSchemaContent.cs: Make actualBaseSchemaType protected (fixes
	build).
	
2004-01-15  Atsushi Enomoto <[email protected]>

	* XmlSchemaComplexContentExtension.cs,
	  XmlSchemaSimpleContentExtension.cs,
	  XmlSchemaSimpleContentExtension.cs,
	  XmlSchemaSimpleContentRestriction.cs,
	  XmlSchemaContent.cs : Added IsExtension. GetXXX() became nonvirtual.
	* XmlSchemaType.cs : 
	  - Added NET_2_0 BaseXmlSchemaType (other members are commented out).
	  - Now BaseSchemaType redirects to new property BaseXmlSchemaType.
	* XmlSchemaComplexType.cs :
	  - Now it fully uses BaseXmlSchemaType above.
	  - Since ValidateXXX() became too huge, I divided them into 
	    CollectXXX() [spec 3.4.1] and ValidateXXX() [spec 3.4.3 / 3.4.6].
	    Schema Components are contributed before constraint check.
	  - Now ContentTypeParticle is distinguished from validating particle
	    which is newly introduced as "ValidatableParticle" (only used in 
	    XsdValidatingReader).
	* XmlSchemaSimpleType.cs : Now it uses BaseXmlSchemaType.
	  capitalized internal members a bit.

2004-01-14  David Sheldon <[email protected]>

        * XmlSchemaSimpleTypeRestriction: Convert pattern facets to be ORed, 
          as per: http://www.w3.org/TR/xmlschema-2/#src-multiple-patterns
          Fixes bug 52841

2004-01-14  David Sheldon <[email protected]>

        * BuiltInDatatype.cs:
	   XsdAnySimpleType - Added Length that returns the string length. 
	   XsdBase64Binary - Added Length, and used more direct, less fussy, 
	       Base64 decoder. 
	   XsdHexBinary - Added Length method

	* XmlSchemaSimpleTypeRestriction: use DataType Length method to
	  determine length to compare against. Stop testing Lenght facets on 
	  QName and Notation types (as per errata)

2004-01-14  Atsushi Enomoto <[email protected]>

	* XmlSchemaComplexType.cs : forgot to commit ;)
	* XmlSchemaUtil.cs : Fixed IsSchemaDatatypeEquals() to return false
	  for comparison between ID and IDREF.

2004-01-14  Atsushi Enomoto <[email protected]>

	* Added SchemaDataValueType.cs.
	* BuiltInDatatype.cs, XmlSchemaDatatype.cs : Adde ParseValueType() on
	  all derived datatype classes.
	* XmlSchemaComplexType.cs : Fixed ContentType value for simple types.
	  Errata-considered simple content derivation check and simple content
	  restriction should check this too.

2004-01-13  Jackson Harper <[email protected]>

	* XmlSchemaComplexType.cs: Comment out line that was breaking the build.
	
2004-01-13  Atsushi Enomoto <[email protected]>

	* XmlSchemaSimpleTypeUnion.cs : The same reason as the previous patch.
	* XmlSchemaComplexType.cs : Now it handles ContentTypeParticle and 
	  ContentType much more presise than before.
	* XmlSchemaElement.cs :
	  Simplified property handling for reference element.

2004-01-13  Atsushi Enomoto <[email protected]>

	* XmlSchema.cs, XmlSchemaComplexType.cs, XmlSchemaElement.cs :
	  Invalid attribute should raise an error, not a warning.

2004-01-13  Atsushi Enomoto <[email protected]>

	* XmlSchemaObject.cs : Fixed error() not to set severity as Warning.
	* ValidationHandler.cs,
	  XmlSchemaSet.cs,
	  XmlSchemaCollection.cs : Throw exception only in case of errors.
	* XmlSchemaCollection.cs : Remove schema from schemaset if exist.
	  (It might not be good to use schemaset, but keep for a while)
	* XmlSchemaContent.cs,
	  XmlSchemaComplexContentExtension.cs,
	  XmlSchemaComplexContentRestriction.cs,
	  XmlSchemaSimpleContentExtension.cs,
	  XmlSchemaSimpleContentRestriction.cs,
	  : added GetBaseTypeName() and GetParticle() (not used yet).

2004-01-11  Atsushi Enomoto  <[email protected]>

	* BuiltInDatatype.cs : internal type should not appear in protected
	  members' signature.

2004-01-11  David Sheldon <[email protected]>

  * BuiltInDatatype.cs : Added XsdOrdering enum, and Compare methods
   to the data-types. Changed AllowedFacets to be a bitfield.

  * XmlSchemaEnumerationFacet.cs,
    XmlSchemaFractionDigitsFacet.cs,
    XmlSchemaLengthFacet.cs,

    XmlSchemaMinExclusiveFacet.cs,
    XmlSchemaMinInclusiveFacet.cs,
    XmlSchemaMinLengthFacet.cs,
    XmlSchemaNumericFacet.cs,
    XmlSchemaPatternFacet.cs,
    XmlSchemaTotalDigitsFacet.cs,
    XmlSchemaWhiteSpaceFacet.cs : Added ThisFacet Property to return facet type


  * XmlSchemaSimpleTypeRestriction.cs: Inherited facets from base types,
    checked which which were allowed on different types. Validated fixed
    facets, duplicated facets and derivation by restriction. Added checking 
    for min/max Inclusive/Exclusive, totalDigits and fractionDigits facets in 
    validation.

2004-01-09  Atsushi Enomoto  <[email protected]>

	* XmlSchemaSet.cs : implemented some members.
	* XmlSchemaCollection.cs : modified to use internal schema set (This
	  class provides more precise schema validation feature and will be
	  commonly used for XPathNavigator2).
	  Added .NET 1.1 .ctor() which takes XmlResolver.
	* XmlSchema.cs : fix related to above changes.
	  Use validation event handler on Read() at all required places.
	  Added .NET 1.1 .ctor() which takes XmlResolver.
	* XmlSchemaComplexType.cs : content type comparison was incorrect.
	  Renamed confusing method.
	* XmlSchemaElement.cs : don't use ContentTypeParticle in 
	  CheckRecursion(), where that property might not be determined yet.
	* XmlSchemaGroupBase.cs : Modified ValidateRecurse() a bit (currently
	  no effect)

2004-01-08  Atsushi Enomoto  <[email protected]>

	* BUGS-MS.txt : added list derivation and facet case.
	* XmlSchemaComplexType.cs :
	  Added some description.  Avoided null reference exception in 
	  some places.  
	  Fixed incorrect 3.4.6 Derivation Valid (Extension) 1.4.1.2.2 and
	  3.9.6 Particle Valid (Extension) 2.
	* XmlSchemaGroupBase.cs : Fixed ParticleEquals() which didn't work
	  properly against sequence and all.

2004-01-08  Atsushi Enomoto  <[email protected]>

	* XmlSchemaObjectTable.cs : Modified enumerator's Current to return
	  DictionaryEntry.

2004-01-03  Atsushi Enomoto  <[email protected]>

	* XmlSchemaDatatype.cs : trivial allocation fix.

2003-12-17  David Sheldon  <[email protected]>

  * BuiltInDatatype.cs : Added whitespace=collapse to data types 
    such as date, dateTime, .... gDay. I think I have them all now.

2003-12-15  Atsushi Enomoto  <[email protected]>

	* BuiltInDatatype.cs : anySimpleType should allow facets.

2003-12-14  David Sheldon <[email protected]>
  
  * BuiltInDatatype.cs : Added code to tell which facets were valid on
    types derived from each basetype.

  * XmlSchemaSimpleTypeRestriction.cs : Complain if an invalid facet
    has been added to a restriction.


2003-12-14  David Sheldon <[email protected]>

  * XmlSchemaSimpleTypeRestriction.cs : Check that min/max/lengths 
    specified are integers. Also made some error messages more useful.

2003-12-08  Atsushi Enomoto  <[email protected]>

	* XmlSchemaSimpleTypeRestriction.cs : patch by David Sheldon. Check
	  if max/min length range is valid.

2003-12-07  Atsushi Enomoto  <[email protected]>

	* BuiltInDatatype.cs : XsdDecimal and XsdInteger defaults whitespace
	  facet as collapse (patch by David Sheldon).
	* XmlSchemaAnnotations.cs, XmlSchemaAny.cs : No more MonoTODOs ;-)
	* XmlSchemaSequence.cs : MapAndSum implementation.

2003-11-17  Atsushi Enomoto  <[email protected]>

	  (for convenience of ObjectSpaces stubbing).

2003-10-25  Atsushi Enomoto  <[email protected]>

	* BuiltInDatatype.cs : XsdByte was incorrectly typed as byte, while
	  the correct binding is sbyte.
	* XmlSchemaAll.cs,
	  XmlSchemaChoice.cs,
	  XmlSchemaSequence.cs,
	  XmlSchemaGroupBase.cs : ActualParticle now considers pointlessness
	  described in WXS structures 3.9.6.
	  Added ValidateRecurse() to support 'Recurse' validation.
	* XmlSchemaComplexType.cs : Removed incorrect content type conformity
	  check.
	* XmlSchemaElement.cs : Implemented 'RecurseAsIfGroup' validation
	  described in WXS structures 3.9.6.  Fixed type derivation check to
	  do only if the base type is not anyType.
	* XmlSchemaSimpleTypeRestriction.cs : Should catch Regex() 
	  construction exception. ValidateList... and ValidateNonList... was
	  in reverse.
	* XmlSchemaUtil.cs : Removed extra MonoTODO. Removed CheckToken().

2003-10-25  Atsushi Enomoto  <[email protected]>

	* BuiltInDatatype.cs : Fixed incorrect inheritance of date and time.
	  Fixed most of date-time related types' ParseValue().
	  Applied Normalize() before parsing values in some ParseValue().

2003-10-23  Atsushi Enomoto  <[email protected]>

	* XmlSchemaAll.cs,
	  XmlSchemaChoice.cs,
	  XmlSchemaGroupBase.cs,
	  XmlSchemaSequence.cs : Now CompiledItems went to XmlSchemaGroupBase.
	* XmlSchemaAny.cs,
	  XmlSchemaElement.cs,
	  XmlSchemaGroupBase.cs,
	  XmlSchemaGroupRef.cs,
	  XmlSchemaParticle.cs,
	  XmlSchemaSequence.cs : Added ParticleEquals() method to compare 
	  whether the particles are equal in the context of WXS part 1 - 3.9.6.
	* XmlSchemaAny.cs : Implemented ValidateDerivationByRestriction().
	* XmlSchemaAnyAttribute.cs : Removed extraneous lines and added my
	  responsibility on this class.
	  Added ValidateWildcardAllowsNamespaceName().
	* XmlSchemaAttribute.cs : Added ValidatedUse which holds post-
	  compilation value of "Use".
	* XmlSchemaAttributeGroup.cs,
	  XmlSchemaAttributeGroupRef.cs : Removed MonoTODO (same as some other
	  classes) since there is no more errors on attribute stuff ;-)
	* XmlSchemaComplexType.cs : complex content extension must block 
	  derivation from any built-in primitive types.
	  Fixed wildcard derivation by restriction.
	  ValidateDerivationByRestriction() now checks attribute related
	  validity of DBR (derivation by restriction).
	  Now uses ParticleEquals() for particle DBR check.
	* XmlSchemaSequence.cs : Fixed to use CompiledItems instead of Items.

2003-10-21  Atsushi Enomoto  <[email protected]>

	* XmlSchema.cs,
	  XmlSchemaUtil.cs : Reduced warning message.
	* XmlSchemaAttribute.cs : NotImplementedException should no more exist.

2003-10-13  Lluis Sanchez Gual <[email protected]>

	* XmlSchema.cs: If the schema element is an empty element, skip it after
	  reading the attributes.

2003-10-09  Atsushi Enomoto  <[email protected]>

	* BuiltInDatatype.cs : Added CLSCompliant attributes to some classes.

2003-10-01  Lluis Sanchez Gual <[email protected]>

	* XmlSchemaUtil.cs: arrayType attribute needs special handling.

	  Added my responsibility on them ;-)

2003-10-01  Atsushi Enomoto  <[email protected]>

	* XmlSchema.cs : Read() should keep current position of XmlReader if
	  it was already positioned to 'schema' element.

2003-09-30  Atsushi Enomoto  <[email protected]>

	* Forgot to append 8/24/2003 ChangeLog.

	  - More datatype support.
	  and so on.

2003-09-14  Lluis Sanchez Gual <[email protected]>

	* XmlSchema.cs: Do not add schema namespace declaration if it is already
	  declared.

2003-08-28  Lluis Sanchez Gual <[email protected]>

	* BuiltInDatatypes.cs, XmlSchemaDatatype.cs: Added double type.

2003-08-24  Atsushi Enomoto  <[email protected]>

	* BuiltInDatatype.cs : XsdDecimal.TokenizedType should be None.
	* XmlSchemaCollection.cs : Add(uri) should not reject chameleon schema.
	  Add() should compile specified schema.

2003-08-08  Lluis Sanchez Gual <[email protected]>

	* BuiltInDatatypes.cs, XmlSchemaDatatype.cs: Added XsdAnyURI,
	  XsdDateTime, XsdDate, XsdTime.

2003-08-07  Atsushi Enomoto  <[email protected]>

	* BuiltInDatatypes.cs : Fixed whitespace facet in XsdToken.
	  Tokenized type of nmtokens and entities is string [].
	* XmlSchema.cs : Changed IsCompile implementation a bit.
	  Compile() should reset compiled contents.
	* XmlSchemaDatatype.cs : Fixed collapsing Normalize().
	* XmlSchemaObject.cs : added CompilationId initialization.

2003-08-05  Lluis Sanchez Gual <[email protected]>

	* XmlSchema.cs: Set IsCompiled to true after compiling.
	  In Compile(): ignore included schemas that do not have a value
	  in SchemaLocation. It means that FindElement can return null
	  if the referred schema was ignored. Added check for that case.
	  Compile schema after reading it.
	* XmlSchemaCollection.cs: The targetNamespace of a schema may
	  be null. Make XmlSchemaCollection work for this case.
	* BuiltInDataType.cs, XmlSchemaDataType.cs: added new primitive
	  types: float, base64Binary, boolean.

2003-08-02  Atsushi Enomoto  <[email protected]>

	* XmlSchema.cs :
	  - Changed missingElementTypeRefs from Hashtable to ArrayList.
	  - Added internal XmlSchemas for keeping imported schemas.
	  - Added private Compile() that takes the original rootSchema and
	    schema location stack for nested inclusion check.
	  - Added basic xs:import and xs:include support.
	  - Compile() is now aware of included XmlSchemaObject items.
	  - Changed Compile() to fill missing elements' types and that of
	    referencing elements.
	  - Read() now adds SourceUri property (although only to itself).
	* XmlSchemaCollection.cs : Implemented Add().
	* XmlSchemaCollectionEnumerator.cs :
	  Changed .ctor() to use schema collection as its argument.
	  Fixed Current to return hashtable's Value, instead of Current 
	  (which returns DictionaryEntry).
	* XmlSchemaComplexType.cs :
	  Added internal static AnyType.
	  Compile() is now searches for its base type into other schemas.
	* XmlSchemaElement.cs : anyType is supported.
	  It now searches for type information after Compile().
	  SetReferedElementInfo() is now changed to SetSchemaType().
	* XmlSchemaObjectTable.cs :
	  It had problems similar to schema collection. Now it uses internal
	  class XmlSchemaObjectTableEnumerator to support GetEnumerator().
	* XmlSchemaParticle.cs : added internal class XmlSchemaParticleEmpty
	  and internal static Empty.

2003-07-26  Atsushi Enomoto  <[email protected]>

	* BuiltInDatatype.cs : XsdIDRefs.ParseValue () should be implemented.

2003-07-24  Atsushi Enomoto  <[email protected]>

	* XmlSchema.cs : Read() now uses XmlSerializer.Deserialize().

2003-07-21  Atsushi Enomoto  <[email protected]>

	* XmlSchema.cs : added support for collecting missing type references
	  at compilation-time.
	* XmlSchemaType.cs, XmlSchemaComplexType.cs, XmlSchemaSimpleType.cs:
	  - Renamed qName to QNameInternal.
	  - Added BaseSchemaType and ContentTypeParticle support.

2003-07-19  Atsushi Enomoto  <[email protected]>

	* XmlSchema.cs, XmlSchemaAll.cs, XmlSchemaAnnotated.cs,
	  XmlSchemaAnnotation.cs, XmlSchemaAny.cs, XmlSchemaAnyAttribute.cs,
	  XmlSchemaAttribute.cs, XmlSchemaAttributeGroup.cs,
	  XmlSchemaAttributeGroupRef.cs, XmlSchemaChoice.cs,
	  XmlSchemaComplexContent.cs, XmlSchemaComplexContentExtension.cs,
	  XmlSchemaComplexContentRestriction.cs, XmlSchemaComplexType.cs,
	  XmlSchemaElement.cs, XmlSchemaGroup.cs, XmlSchemaGroupRef.cs,
	  XmlSchemaIdentityConstraint.cs, XmlSchemaImport.cs,
	  XmlSchemaInclude.cs, XmlSchemaKey.cs, XmlSchemaKeyref.cs,
	  XmlSchemaNotation.cs, XmlSchemaObject.cs, XmlSchemaRedefine.cs,
	  XmlSchemaSequence.cs, XmlSchemaSimpleContent.cs,
	  XmlSchemaSimpleContentExtension.cs,
	  XmlSchemaSimpleContentRestriction.cs, XmlSchemaSimpleType.cs,
	  XmlSchemaSimpleTypeList.cs, XmlSchemaSimpleTypeRestriction.cs,
	  XmlSchemaSimpleTypeUnion.cs, XmlSchemaUnique.cs,
	  XmlSchemaXPath.cs, 
	  As to Compile() and Validate(),
	  - Added CompilationId and check it while compiling schema components.
	  - Code refactory. Replaced literal xmlns with XmlSchema.Namespace
	  - Replaced XmlSchemaInfo with compiling XmlSchema itself (XmlSchema
	    also has PSVI components inside it, so passing itself seems enough).
	  - Related to above change, IDCollection was moved to XmlSchema, and
	    blockDefault/finalDefault/blockResolved/finalResolved resolution
	    was changed to reference only to schema.BlockDefault/FinalDefault.
	  - The similar change has done against XmlSchemaForm related stuff.
	  - Changed compilation order of schema type definitions (it is
	    workaround). First it compiles types, and then it compiles others.
	* XmlSchemaElement.cs : added ElementType PSVI contribution support.

2003-07-19  Atsushi Enomoto  <[email protected]>

	* BuiltInDatatypes.cs, XmlSchemaDatatype.cs :
	  Added decimal and its derived datatypes.
	  Added abstract XsdAnySimpleType.

2003-07-15  Lluis Sanchez Gual <[email protected]>

	* BuiltInDatatype.cs,
	  XmlSchemaDatatype.cs : added unsignedByte type support.

2003-07-14  Lluis Sanchez Gual <[email protected]>

	* XmlSchemaDatatype.cs: Fixed compiler warning.

2003-07-12  Atsushi Enomoto  <[email protected]>

	* BuiltInDatatype.cs,
	  XmlSchemaDatatype.cs : added NOTATION type support.

2003-07-06  Atsushi Enomoto  <[email protected]>

	* added BuiltInDatatype.cs.
	* XmlSchemaDatatype.cs : [GetType()] added support for some 
	  built-in datatypes.

2003-05-05  Atsushi Enomoto  <[email protected]>

	* XmlSchemaAnnotation.cs : It depended on incorrect ReadNode().

2003-02-19  Atsushi Enomoto  <[email protected]>

	* XmlSchemaAnnotation.cs : expect the correct closing tag on <appinfo>
		and <documentation> elements. (patch by Peter Pentchev)
	* XmlSchemaObjectEnumerator.cs : cast properly to XmlSchemaObject 
		instead of XmlSchema. (patch by Peter Pentchev)

2002-07-23  Duncan Mak  <[email protected]>

	* XmlSchemaException.cs: Partiall implement the ISerializable
	methods. It's not clear now SourceSchemaObject should be deserialized.

2002-07-22  Tim Coleman  <[email protected]>
	* XmlSchema.cs: Removed isCompiled which is defined as internal
		in XmlSchemaObject.

2002-06-18  Dwivedi, Ajay kumar <[email protected]>
	
	* XmlSchema: Started work on Validate methods

2002-06-18  Dwivedi, Ajay kumar <[email protected]>
	* XmlSchema: The Read and Write methods are no more [MonoTODO] :)
	
	* XmlSchemaAppInfo: Xml Markup is now being read.
	
	* XmlSchemaDocumentation: Xml Markup is now being read.

	* All: Unhandled attributes are being handled properly.
	       
	* All: Reordered the properties in all cs files to match with MS
	       Implementation. This was required since the order is importatnt
	       for the XmlSerializer.
	
2002-06-14  Dwivedi, Ajay kumar <[email protected]>
	* General: Fixed a few more Bugs

2002-06-10  Dwivedi, Ajay kumar <[email protected]>
	* XmlSchemaReader: A Wrapper class around XmlReader with customized
	  methods to suit reading a schema.
	* General: Implemented Read() method for the schema. There are only
	  a few minor bugs remaining.

2002-05-25  Dwivedi, Ajay kumar <[email protected]>
	* BUGS.txt: New file to keep track of bugs

	* ALL: All classes are initialized exactly as in .NET except
	       1. inclusion of language attribute in schema
	       2. ComplexContent's Particle is initialized to null whereas .NET 
	          to some internal implementation. IMO Null is more appropriate

	* ALL: Changed the Compile methods to return the count of errors.

	* ALL: Complile methods are almost complete. Pass 1453 of 3061 tests.
	       This number should shoot up if we write a parser to read the
	       Schema instead of using reflection (which is slower too)

2002-05-04  Dwivedi, Ajay kumar <[email protected]>
	* XmlSchemaUtil.cs: New file added. 
	
	* Parser.cs: New file Added. Unused at the moment.

	* XmlSchemaObjectCollection: Fixed GetEnumerator
	
	* General: Preprocessing for Attributes and SimpleTypes completed.

2002-04-26  Duncan Mak  <[email protected]>

	* ValidationHandler.cs: New file.

	* XmlSchemaInfo.cs: New file.

	* *.cs: More updates from Ajay.
