        IsPrimaryKey property

2004-06-01  Atsushi Enomoto  <[email protected]>

	* DataRow.cs : ColumnsChanged event is not required in .ctor().

2004-06-01  Atsushi Enomoto  <[email protected]>

	* XmlDataReader.cs : type change is required before setting value
	  string to row item.

2004-05-31  Atsushi Enomoto  <[email protected]>

	* DataSet.cs : Loop-break of the last fix was incorrect.

2004-05-31  Atsushi Enomoto  <[email protected]>

	* DataSet.cs : When a row has no parent row but the table has parent
	  relation(s), that row had been always ignored.

2004-05-31  Atsushi Enomoto  <[email protected]>

	* XmlDataInferenceLoader.cs : Fixed GetMappedTable() that incorrectly
	  rejected same-named tables in different hierarchy. Thanks to Boris.

2004-05-31  Atsushi Enomoto  <[email protected]>

	* XmlDiffLoader.cs : Added some Skip() that is required not to go to
	  infinite loop. Thanks to Boris for this fix.

2004-05-31  Atsushi Enomoto  <[email protected]>

	* XmlDataInferenceLoader.cs : XmlSchema elements should not be infered.
	  Thanks to Boris for this fix.

2004-05-30  Atsushi Enomoto  <[email protected]>

	* DataTable.cs : serialization .ctor() should use XmlReadMode.DiffGram
	  for ReadXml(). Thanks to Boris.

2004-05-27  Boris Kirzner  <[email protected]>
	* DataRow.cs : 
		- CheckReadOnlyStatus : use typed (and faster comparing).
		- EndEdit : bug fix - do not dispose record if it holds original version.
		- SetValuesFromDataRecord : Take care about autoincrement columns.
		

2004-05-27  Atsushi Enomoto  <[email protected]>

	* MergeManager.cs : don't output debug message to Console.

2004-05-27  Atsushi Enomoto  <[email protected]>

2004-05-27  Umadevi S <[email protected]>
         * DataRelationCollection.cs - fixed nunit test errors

2004-05-27  Umadevi S <[email protected]>
	 * DataTableCollection.cs - fixed nunit test errors

2004-05-21  Atsushi Enomoto  <[email protected]>

	* DataColumnCollection.cs : NullReferenceException was thrown when
	  the table was not found.
	* DataRowCollection.cs :
	  Find() just returns null for null value under MS.NET 1.1.
	  RemoveAt() should also avoid to call AcceptChanges() like Remove().
	* UniqueConstraint.cs : in AssertConstraint() throw ConstraintException
	  directly under MS.NET (for nunit test).

2004-05-21  Atsushi Enomoto  <[email protected]>

	* XmlSchemaDataImporter.cs : Setting startindex in LastIndexOf() 
	  caused problem on qualified name to get schema Field name.

2004-05-21  Atsushi Enomoto  <[email protected]>

	* XmlDataReader.cs : Now data reader is namespace aware in all places.
	  When table's namespace is different, it entered to infinite loop.

2004-05-19  Boris Kirzner  <[email protected]>
	* MergeManager.cs : AdjustSchema now updates by reference new created table,
	so in Merge you do not need to lookup for it (were unable to do this for unnamed tables).
	Code styling.
	
2004-05-19  Boris Kirzner  <[email protected]>

	* DataColumn.cs : In set_Item[int] - if autoincrement, adjust next autoincrement value.
	* DataColumnCollection.cs : fixed parantethes.
	* DataRow.cs : 
		- AcceptChanges : do nothing if row state is unchanged.
		- GetChildRows, GetParentRows  : bug fix (use correct index).
	* DataRowCollection.cs : bug fix (compare all row's values).
	* DataTable.cs : bug fix (use correct row version).
	
2004-05-20  Atsushi Enomoto  <[email protected]>

	* XmlSchemaDataImporter.cs : xs:positiveInteger is mapped to ulong.
	  When content type is Mixed, text column is not required (it is
	  required only when the complex type has no particle). 
	  "Repeated element" column is also created (considering maxOccurs=0 
	  and complex content extension).

2004-05-20  Atsushi Enomoto  <[email protected]>

	* XmlSchemaDataImporter.cs : XmlSchemaGroupBase was not handled 
	  properly.

2004-05-20  Atsushi Enomoto  <[email protected]>

	* XmlSchemaDataImporter.cs : Removed unused code and extra MonoTODO.
	  Fixed relation inference to consider attribute XPath.

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

	* DataColumn.cs : Fixed set_Item[int]. Convert.ToInt64(DBNull.Value)
	  always fails.

2004-05-19  Boris Kirzner  <[email protected]>

	* DataColumn.cs - removed default member attribute.

2004-05-19  Boris Kirzner  <[email protected]>

	* DataColumn.cs,
	  DataColumnChangeEventArgs.cs,
	  DataColumnCollection.cs,
	  DataRow.cs,
	  DataRowCollection.cs,
	  DataTable.cs,
	  Index.cs : Data storage in the row is redesigned. Now data is stored in 
	  typed containers inside DataColumn. Row holds its versions as indexes inside
	  each of data container, accessed through the row that holds it.

2004-05-19  Boris Kirzner  <[email protected]>

	* UniqueConstraint.cs - added comment.
	
2004-05-19  Atsushi Enomoto  <[email protected]>

	* XmlDataInferenceLoader.cs : Don't add already-existing DataTable to
	  DataSet.

2004-05-17  Atsushi Enomoto  <[email protected]>

	* DataSet.cs,
	  XmlDataInferenceLoader.cs,
	  XmlDataReader.cs,
	  XmlSchemaDataImporter.cs : XmlDecode every local name to read and
	  XmlEncode every local name to write. This should fix bug #58268.

2004-05-17  Atsushi Enomoto  <[email protected]>

	* DataSet.cs : Implemented ignored namespaces in InferXmlSchema().
	  Supported repeated elements. Removed MonoTODOs.
	* XmlDataInferenceLoader.cs : Design change to support ignored
	  namespace and repeated elements.
	* XmlSchemaDataImporter.cs : Added mapping support classes.

2004-05-15  Atsushi Enomoto  <[email protected]>

	* CustomDataClassGenerator.cs :
	  Added property parent "[foo]Row" and children "Get[foo]Row" support
	  for custom DataRow classes.
	  Fixed DataColumn property accessibility (public --> internal).

2004-05-14  Atsushi Enomoto  <[email protected]>

	* CustomDataClassGenerator.cs :
	  - Put classes inside custom DataSet class.
	  - Added automatic DataRelation creation support.
	  - Added Constraints creation support. That is done separate from
	    relations, since they might be independently created.
	  - Added non-MS public DataRelation fields.
	  - Removed extraneous "DataRelation type generation" code.
	  - Fixed custom_dataset.Initialize() not to create "c" field that
	    was created more than once.
	  - Implemented AddxxxRow() that takes parameters for every column.

2004-05-14  Atsushi Enomoto  <[email protected]>

	* XmlSchemaDataImporter.cs : When primary key is used more than once,
	  DataRelation borked because of empty parent column name.

2004-05-14  Atsushi Enomoto  <[email protected]>

	* XmlSchemaDataImporter.cs : When Creating constraints with related
	  to DataRelation creation, also set PrimaryKey to the parent table.

2004-05-14  Atsushi Enomoto  <[email protected]>

	* XmlSchemaDataImporter.cs : 
	  Design change to add indirect table and relation structures.
	  Support for "relation" annotation for local element.
	  Support for repeatable simple element column (maxOccurs > 1).
	  Fixed handling of Nested property on DataRelation (for globally
	  annotated relation, Nested is false).

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

	* DataRow.cs : Added DataElement property to avoid storing every row-
	  element mapping. It stored even for nodes that should be removed.

2004-05-13  Umadevi S <[email protected]>

	* RelationshipConverter.cs - Stubbed this class
	* DataRelation.cs - added TypeConveterAttribute

2004-05-13  Umadevi S  <[email protected]>

	* DataColumnCollection.cs - Added ResDescriptionAttribute

 	* DataViewSetting.cs - Added TypeConverterAttribute
	
2004-05-12  Atsushi Enomoto  <[email protected]>

	* DataRow.cs : Added XmlDataElement initialization code.

2004-05-11  Atsushi Enomoto  <[email protected]>

	* XmlDataInferenceLoader.cs :
	  It now requires XmlDocument as input.  Improved identification of
	  DataSet element.  Removed extra lines.
	  Moved boresome design notes to bottom of the source and
	  added standalone runnable driver (not included on build).
	* DataSet.cs :
	  Update with related to the change above.
	  WriteXml() should call Flush() after writing. This fixes bug #58327.
	* XmlSchemaDataImporter.cs :
	  Improved indentification of DataSet element.

2004-05-11  Gert Driesen ([email protected])
	* DataTable: marked initStatus enum internal

2004-05-09  Gert Driesen ([email protected])
	* DataTable.cs: removed TypeConverterAttribute, marked RowsExist
	methods internal
	* DataRowView.cs: removed extra Error property
	* DataRow.cs: reduced accessibility of CollectionChanged method 
	to private
	* DataColumnPropertyDescriptor.cs: made class internal
	* DataColumn.cs: removed extra TypeConvertorAttribute
	* ConstrainCollection.cs: marked PostEndInit method internal

2004-05-07  Atsushi Enomoto  <[email protected]>

	* DataSet.cs : 
	  In WriteXmlSchema(), when complex type contains simple type content
	  attributes must not added to XmlSchemaComplexType directly. It
	  causes schema compilation error.
	  DataRelation should not be output when related columns are hidden.

2004-05-07  Atsushi Enomoto  <[email protected]>

	* XmlDataInferenceReader.cs : Added. It does InferXmlSchema() (it is
	  also expected to do ReadXml(), but I will remove that feature and
	  support column reordering).
	* XmlSchemaDataImporter.cs : Always initialize dataset name.
	  Always set Nested and primary key for parent table.
	* XmlDataReader.cs : Now it is used.
	  Top level element might not match to dataset name nor any table 
	  name, but still possible to read content tables.
	  Handle empty element correctly in some places.
	  Handle Fragment mode (read up XmlReader to the end).
	* DataSet.cs : Modified InferXmlSchema() and ReadXml() to use
	  XmlDataInferenceLoader and XmlDataReader.

2004-05-06  Atsushi Enomoto  <[email protected]>

	* DataSet.cs :
	  Eliminated CRLF injection.
	  More clear message in Clear().
	  Updates reflecting XmlSchemaDataImporter change.
	  Added duplicate check for XmlSerializerNamespaces in BuildSchema().
	  Don't use xmlns attribute for UnhandledAttributes (its not mandatory
	  but that depends on different behavior from ms.net).
	  Set locale also for DataTable.
	  Add xs:element only when target namespace matches to the
	  element's namespace. Otherwise, add xs:import for external namespace.
	  Put xs:sequence for dataset element's particle _only when_ actual
	  contents exist.

2004-05-06  Atsushi Enomoto  <[email protected]>

	* XmlDataReader.cs : Added. This class will work better when our
	  schema inference and schema read engine gets improved. (It contains
	  standalone testable Driver class.)

2004-05-06  Atsushi Enomoto  <[email protected]>

	* ForeignKeyConstraint.cs : Check step change. Existence then column
	  validity. just for tests.
	* XmlSchemaDataImporter.cs : code simplification. reduced extraneous
	  fields.

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

	* DataSet.cs : Ignore empty content only when output type is diffgram.

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

	* CustomDataClassGenerator.cs : Modified that DataSet contains each
	  DataTable field so that each table property can access them directly.
	  (plus, modified standalone code driver code: shouldn't affect)

2004-05-05  Boris Kirzner  <[email protected]>

	* DataView.cs , DataRowView.cs : Added implementation to basic methods and properties.
	  
2004-05-05  Atsushi Enomoto  <[email protected]>

	* XmlSchemaDataImporter.cs : 
	  SimpleContent column support.
	  Annotated relation support.
	  Top-level element is counted only when its type is complex.
	  xs:anyType is no longer treated as complex type.
	  dataset existence is mandatory now. 
	  Improved DataType and DefaultValue support.
	  Attribute namespace is properly handled now.
	  Prohibited attribute is now treated as hidden column.
	  Reject list or union simple type.

	  Still incomplete 1) to read relationship in some cases, 2) to 
	  determine whether an element is dataset or table, 3) thus to
	  exclude extraneous column, 4) to remove extraneous *_Id column.

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

	* DataTable.cs :
	  We had better reuse DataSet's ReadXmlSchema() and ReadXml() in
	  serialization .ctor() (thus schema read/inference should be easier).
	  DataRowSorter should consider Table's Locale.

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

	* DataColumnCollection.cs : We already had AutoIncrementValue(), so
	  use it instead of duplicating logic.

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

	* ConstraintCollection.cs :
	  Use Table.CaseSensitive and Table.Locale to compare strings.
	  Duplicate constraint name exception does not occur under .NET 1.1.

2004-05-04  Lluis Sanchez Gual  <[email protected]>

	* XmlSchemaDataImporter.cs: Added little type check.

2004-05-04  Lluis Sanchez Gual  <[email protected]>

	* DataSet.cs: Implemented support for runtime serialization. Fixed support
	  for xml serialization.
	* XmlDiffLoader.cs: Skip diffgram element when it is empty.

2004-04-30  Umadevi S  <[email protected]>
	* DataColumnCollection.cs : Fixed nunit test errors, removed TODOs
	* DataTableCollection.cs  : Tested and removed TODO
	* TypedDataSetGeneratorException.cs : Fixed a couple of TODOs	

2004-04-29  Atsushi Enomoto  <[email protected]>

	* DataRow.cs : My previous patch unintentionally reverted Boris patch.

2004-04-29  Boris Kirzner <[email protected]>

	* UniqueConstraint.cs : Constraint columns becaomes unique after adding constraint ifand only if 
	constraint is defined on single column.

2004-04-29  Atsushi Enomoto  <[email protected]>

	* DataRowCollection.cs : .NET 1.1 throws InvalidConstaintException,
	  not ArgumentException (maybe changed after 1.1).

2004-04-29  Atsushi Enomoto  <[email protected]>

	* DataRow.cs : When Column was added and it was AutoIncrement column,
	  it extended the item object array incorrectly.
	  (Plus tiny comment and incorrect indentation fix.)

2004-04-29  Boris Kirzner <[email protected]>

	* MergeManager.cs : added ( incomplete yet ) support for merging DataSet schema.

2004-04-29  Boris Kirzner <[email protected]>

	* DataRow.cs : Bug fix in CopyValuesToRow().
	
2004-04-29  Boris Kirzner <[email protected]>

	* UniqueConstraint.cs : There is no reason to mark constraint's columns as unique, because
	  each of the columns should not be unique, but only all the constraint's columns together.
	
2004-04-28  Boris Kirzner <[email protected]>
	* DataRow.cs :
	  - Perfomance fixes: 
		- Added using of list of autoIncrement columns
		- SetColumnValue receives also DataColumn to avoid duplicate lookup in DatacolumnCollection
	  - Fix in CheckNullConstraints
	  - Fix in this[] and HasVersion() : when evaluating an expression deleted rows values can be accessed.
	  - Fix in SetColumnValue() , added CanAccess() method to avoid case of accessing internal array values berore it actually allocated.
	  - Added onColumnRemoved() method to threat column removal accurately.
	
	* DataRowCollection.cs :
	  - Added using of DataRow._nullConstraintViolation (for perfomance fix in EndLoadData())
	  - Added method onColumnRemoved() - calls each row's onColumnRemoved() (to ensure column removal is treated accurately)
	
	* DataTable.cs :
	  - Call DataRowCollection.onColumnRemoved() in OnRemoveColumn() (to ensure column removal is treated accurately)
	
	* DataColumnCollection.cs :
	  - Perfomance fixes :
		- collection holds a list of its autoIncrement columns (avoids unnesessary lookup through whole collection)
		- collection holds mapping from column names to DataColumn objects (avoids lookup through whole collection).
		- automatic creation of column names rewrited (bug fixes + perfomance improvement)
	
	* DataColumn.cs :
	  - Uses autoincrement list of a table

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

	* XmlDataLoader.cs : Even when it should ignore schema, it was 
	  infering schema.
	* XmlSchemaDataImporter.cs : DataRelation creation support.
	  Improved "DataSet" element handing. When attributes are on the
	  element, it is not a "DataSet" element.
	  Fixed parent key column name.
	  Unique name creation is not required. Just raise an error.
	  Fill facet also for attribute types.

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

	* DataRow.cs : Null check for CheckReadOnlyStatus() and
	  CheckNullConstraints(), with some coding guideline fixes.
	  Type check should be done by Type instance comparison.

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

	* DataColumnCollection.cs : When add a column to the collection, fill
	  auto-increment column.

2004-04-26  Boris Kirzner <[email protected]>

	* DataColumn.cs : Small perfomance fix (avoid unnesessary string concatenation).
	
2004-04-26  Atsushi Enomoto  <[email protected]>

	* CustomDataClassGenerator.cs : Added.
	* TypedDataSetGenerator.cs : Implemented Generate().
	  Changed GenerateIdName() to call CustomDataClassGenerator.MakeSafeName
	* XmlSchemaDataImporter.cs : Table Locale should be supplied.

2004-04-25  Boris Kirzner <[email protected]>

	* DataTable.cs : Small perfomance fix (avoid unnesessary string concatenation).
	
2004-04-25  Boris Kirzner <[email protected]>

	* Constraint.cs : Small perfomance fix (avoid unnesessary string concatenation).

2004-04-23 Umadevi S ([email protected])
	*  DataRow.cs: Checked BeginEdit,EndEdit,CancelEdit and Delete methods
	   - Added error handling to the above methods

2004-04-22  Atsushi Enomoto  <[email protected]>

	* DataSet.cs : Data should be read when mode is IgnoreSchema (well,
	  the support is incomplete yet).
	* XmlDataLoader.cs : 
	  Reverted ReadModeSchema() argument change. XmlReadMode would be 
	  useful to handle IgnoreSchema.
	  Don't overwrite DataSetName when mode is not such kind.
	  Set Prefix and Namespace as well as DataSetName.
	  AllowDBNull looks set false by default for element column.
	  Set unique constraint as primary key when infering the table schema.

2004-04-21  Atsushi Enomoto  <[email protected]>

	* DataSet.cs : 
	  Never set null string for Prefix and Namespace.
	  In InferXmlSchema() when null XmlReader is passed, just do nothing.
	  In WriteXmlSchema(string), earlier try block.
	  In BuildSchema(), try to add serialization namespaces for each
	  namespaces in DataSet/DataTable/DataColumn.
	  Removed namespace argument from WriteColumnAsElement() and don't
	  overwrite when namespace is "". This fixes bug #57330.
	* DataColumn.cs : For Namespace and Prefix, never set null.

2004-04-21  Boris Kirzner <[email protected]>

	* XmlSchemaMapper.cs : Check for not null unique constraint in ReadXmlSchemaKeyref()
	  before creating and adding foreign key constraint and relation. 

2004-04-21  Boris Kirzner <[email protected]>

	* MergeManager.cs : In AdjustSchema() source table clone should be added
	  and not the table itself. 

2004-04-21  Boris Kirzner <[email protected]>

	* DataSet.cs : 
	  - CaseSensitive : Additional fix (removed unnesessary assignment).
	  - CopyProperties : Do not try to copy ExtendedProperties if the collection is empty.

2004-04-21  Boris Kirzner <[email protected]>

	* DataTable.cs : Ensure that DataSet property is not null before using it in Clear().
	  
2004-04-20  Boris Kirzner <[email protected]>

	* DataTable.cs : 
	  - EndLoadData() : perfomance fix in case of null constraint violation
	    during data load (also in DataRow.cs).
	  - CaseSensitive : If DataTable belongs to DataSet it should always use
	    DataSet.CaseSensitive untill explicitly changed.
	  - CopyProperties() : do not try to copy ExtendedProperties if the collection is empty.
	  
	* DataRow.cs :
	  - Pefromance fix in case of null constraint violation
	    during data load (also in DataTable.cs).
	  - CollectionChanged() : use correct column number after new DataColumn was added
	    (differs in case some DataColumn was previosly removed).
	  - EndEdit() - throw away  proposed values only after CheckChildRows() complete.

2004-04-20  Boris Kirzner <[email protected]>

	* DataColumnCollection.cs : Since unique constraint is added now
	  in DataColumn.SetTable() the additional creation of constraint in 
	  DataColumnCollection.Add() is redundant and causes exception - fixed.
	  
2004-04-19  Atsushi Enomoto  <[email protected]>

	* XmlDataLoader.cs : Added "never add data rows" mode.
	  Removed unused code. However, it is temporary fixes to unify
	  ReadXml() and InferXmlSchema().
	* DataSet.cs : Implemented InferXmlSchema(), though it is incomplete.

	  I'll create another XmlDataLoader since there are many problems
	  such that 1) it is too waste to read the entire xml into an
	  XmlDocument, 2) it does not handle attributes correctly, and 3) it
	  must handle "ignored namespaces".

2004-04-19  Atsushi Enomoto  <[email protected]>

	* Added XmlSchemaDataImporter.cs (new schema reader).
	* DataSet.cs : Use XmlSchemaDataImporter (right now for DataSet only)
	  for ReadXmlSchema().
	  Let schema reading work to ReadXmlSchema().
	  Don't return ReadSchema when argument read mode was DiffGram.

2004-04-15 Umadevi S ([email protected])
	*  Updated Clone/Copy methods in DataSet along with Testcase
	*  ForeignKeyConstraint.cs - special ctor implemented 
	    Logic : ParentTable in the ctor - Since only name is given (not the DataTable object), we cannot associate any DataTable or DataSet right now.  So, only possible way is to do it when AddRange() is called. The ParentTable is searched in the DataSet  to which the calling DataTable belongs. And make the calling DataTable as ChildTable. In the PostAddRange() method check is addedd to perform the assignment of parent and child data columns once the information becomes available (When AddRange is called).
	* Changes in  ConstraintCollection.cs for the above
        Add (Constraint) - A check is performed to see if the constraint is ForeignKeyConstraint and whether data columns  are validated.  If no, whether it is called with AddRange(), If no, an Exception is thrown. AddRange() - PostAddRange() is called on the ForeignKeyConstraint object with the "table" as argument. Thanks to Deepak for the patch.
	

2004-04-15  Atsushi Enomoto  <[email protected]>

	* XmlSchemaMapper.cs : set parent key and foreign key info to 
	  DataRelation when reading refkey constraints.
	  Supply constraint name for fkey.

2004-04-15  Atsushi Enomoto  <[email protected]>

	* XmlDataLoader.cs : Don't overwrite existing DataSetName. When read
	  mode is Auto, just ignore the schema if there is already schema info.
	* DataSet.cs : Similarly ignore schema info for XmlReadMode = Auto.

2004-04-14  Atsushi Enomoto  <[email protected]>

	* DataSet.cs :
	  - In MS output, XML declaration looks to have standalone decl (yes).
	  - ReadXml(reader) just calls to ReadXml(reader, XmlReadMode.Auto)
	  - ReadXml(reader, mode)
	    1) return originally specified mode, instead of (always) Auto. 
	    2) Check empty reader.
	    3) Check diffgram schema and content separately.
	    4) When diffgram exists, remaining (the same-level) contents 
	       won't be consumed. 
	    5) Similar fact should be applied, but somewhat different. 
	       InferSchema and IgnoreSchema just skips, Fragment reads both
	       schema and content, others just reads schema.
	  - Removed unused code.
	* XmlDataLoader.cs :
	  - Read() should skip in some ReadMode.
	  - Don't compare schema element name as case-insensitive (well,
	    should schemas be checked here?)
	  - Avoided BuildDocument() not to create confusing DataSet
	    document element.
	  - Don't add any tables when reader has single element.
	* XmlDiffLoader.cs :
	  When target table was not found, MS.NET doesn't raise an error.
	* XmlSchemaMapper.cs :
	  When XmlSchema.Read() left xml reader at </xs:schema>, read once.

2004-04-13  Atsushi Enomoto  <[email protected]>

	* DataSet.cs :
	  - InferXmlSchema(): Throw explicit NotImplementedException now.
	  - Don't put XML declaration everywhere. Write just for filename arg.
	  - xmlns="" should not be written. Maybe WebService problem is 
	    because default namespace is overwritten. This patch will keep
	    the WS problem away and actually fixes some unit tests (i.e. use
	    explicit String.Empty for null namespace in WriteStartElement()).
	  - MoveToContent() should always be called, not only when 
	    LocalName="xml". It will ignore prolog (DTD, PI, comment etc.).
	  - Even XmlReadMode is DiffGram, reader might not be "diffgram"
	    element. As to MSDN, diffgram does not contain schema.

	* DataTable.cs: made _initStatus private so that System.Data is CLS
	compliant.

	*  UniqueConstraint.cs:
	*  ConstraintCollection.cs:
	*  DataTable.cs:
	- Implemented a Constructor for UniqueConstraint.cs
	- Used  EndInit on DataTable  to call a delegate which adds the
	  constraints passed to the most recent call of AddRange().Used
	  AddRange() on ConstraintCollection to check whether
	  DataTable.BeginInit has occurred.  If yes, save the argument
	  constraint collection passed, then return.  If no, Check whether the
	  constraints are of type UniqueConstraint and initialized with the
	  special constructor  If yes Initialized the table property of this
	  UniqueConstraint object with table assosciated with the current
	  instance of ConstraintCollection class.

	* DataRow.cs: Fixed an attribute
	* DataSet.cs: Fixed the modifiers

2003-03-06  Aleksey Demakov <[email protected]>

	* DataTableCollection.cs: The Contains (string name),
	IndexOf (string name) methods, and item[string name] indexer
	now behave more like .NET with respect to case-sensitivity.
	That is if there is an exactly matching item then this one is used.
	If there is only one item differing in case then it used.
	If there are more than one item differing in case then
	Contains returns false, IndexOf returns -1, and item[]
	throws an ArgumentException.

	* ExpressionElement.cs: More implementation. 
	
2003-02-28  Alan Tam <[email protected]>
	* DataSet.cs: Changed WriteTable so that it now calls the newly written
	WriteObjectXml to direct the call to the respective XmlConvert method.

	* DataColumn.cs: Fixed wrong storage representation of Expression
	(using empty string instead of null) so that ToString() returns nothing.
	* DataColumnCollection.cs: Reimplemented GetNextDefaultColumnName so that
	auto column naming now works as expected. Reimplemented some Add methods
	to eliminate code duplication.

2003-02-19  Ville Palo <[email protected]>

	* DataTable.cs: DataTable.CaseSensitive follows parent 
	DataSet.CaseSensitive property if DataTable.CaseSensitive has never
