	exception if no WriteStartElement exists.

2002-03-20  Duncan Mak  <[email protected]>

	as child nodes so updated to reflect that.

	* XmlDocument.cs, XmlElement.cs, XmlNode.cs: Moved code that was
	duplicated in XmlDocument and XmlElement into XmlNode so that it
	wouldn't have to be duplicated in XmlAttribute, too.

2002-03-08  Kral Ferch <[email protected]>

	* XmlNodeList.cs, XmlDocument.cs, XmlLinkedNode.cs,
	XmlNode.cs: Formatting.
	
	* XmlNodeListChildren.cs: Implementation of XmlNodeList

	XmlNodes only have ref to owner doc and parent nodes now.
	
	* XmlLinkedNode.cs: Added NextLinkedSibling internal property
	and ref to next sibling to support walking our circular child
	node list.
	
	* XmlDocument.cs: Added ref to last child node and overrides
	XmlNode's internal LastLinkedChild property to support walking
	our circular child node list.

	* XmlTextReader.cs: Apparently Microsoft's implementation treats
	namespace declarations as attributes so we do now, too.

	* XmlDocument.cs, XmlElement.cs, XmlNode.xs, XmlNodeList.cs,
	XmlNodeListAsArrayList.cs: Multiple fixes necessary to get
