	* XmlDocumentType.cs :
	  modified private DTD to dtd and added internal DTD (the same thing).
	* XmlElement.cs :
	  Fixed SetAttributeNode() to check if specified attribute is already
	  set to the other element. In fact it is W3C DOM's specification but
	  MS.NET 1.0 failed to catch it.
	* XmlTextReader.cs :
	  ReadAttributeValue() should check if the value of the attribute is
	  already read when the whole value is entity reference.
	  Also, Name of text nodes should be "", not "#text"
