	* DTDObjectModel.cs :
	  - Added validation error check (and AddError(), Errors).
	  - Fixed ComputeDefaultValue() to handle various references correctly.
	  - DTDEntityDeclaration.EntityValue became property, and added
	    LiteralEntityValue. The new one holds resolved value.
	    Added ResolveExternalEntity(). It now required root in .ctor().
	* DTDValidatingReader.cs :
	  - Now it handles namespaced attributes (as input to xsd validator).
	  - Added XmlResolver property as usual XmlReader.
	  - Added currentEntityHandling field so that it can stand changing
	    XmlValidatingReader's EntityHandling dynamically.
	  - FilterNormalization() now requires name for getting datatypes and
	    can stand for non-current attribute normalization.
	  - Splitted ReadContent() from Read() that can be called recursively
	    when expanding entities.
	  - Now handles Entity not found error *after* resolution of entities,
	    as MS.NET does.
	  - Read()ing DTD checks its Errors and raises validation error events.
	    In some situations, DTD parsing may detect VC error, not WFC error.
	    It also strictly checks NData existence.
	  - Handling of entity-resolved text is a bit changed and Read()ing
	    element, endElement, cdata now changed to switch collecting text
	    and collected text.
	  - content type ANY should allow texts.
	  - Added enumerated attribute validity check.
	  - Added Name/Names creation rule check for ID/IDREF/IDREFS.
	  - Added entity existence check for ENTITY/ENTITIES attributes.
	  - Added NMTOKEN creation rule check for NMTOKEN/NMTOKENS.
	  - Fixed to remove extraneous #REQUIRED check.
	  - Contributing default attribute is now only applied to the case
	    ValidationType is DTD or None.
	  - ResolveEntity() now handles external entities.
	    Added Mono.Xml.IXmlParserContext interface support.
	* XmlDocumentType.cs : Fixed to use BaseURI to build DTD model.
	* XmlTextReader.cs :
	  - Fixed ReadAttributeValue() to reset returnEntityReference.
	  - Added bool MaybeTextDecl only for ResolveEntity().
	  - Fixed ReadWhitespace(). In fact its value is considered even if it
	    is in the end of the XML.
	  - Fixed ReadXmlDeclaration(). Now skips text declaration.
	  - CompileDTDSubset() now checks IGNORE/INCLUDE section end balances.
	  - ReadContentSpec() should set OrderType = OR for mixed model.
	    Fixed to set content element name correctly.
	  - ImportAsPERef() now skips Text declaration.
	  - Type of enumerated default attributes shold be string.
	  - Undeclared PE error is now handled as DTD's VC error, not
	    XmlTextReader's WFC error.
	* XmlValidatingReader.cs : BaseURI should provide that of
	  original XmlReader's when read was not started yet.
	  Fixed XmlResolver to delegate to DTDValidatingReader.

	* XmlAttributeCollection.cs : Acquiring attList declaration is
	  insufficient especially in case of lack of elementdecl.
	* XmlChar.cs : (Maybe this is compact than XmlConstructs.)
	  added IsWhitespace(),IsNCNameChar(),IsName(),IsNCName(),IsNmToken(),
	  IsPubid(). Copies IsValidIANAEncoding() from XmlConstructs.

	* XmlInputStream.cs : Removed "version" declaration check. It should
	  be done by XmlTextReader.

	* XmlNodeReader.cs : added internal GetInternalParserContext() and now
	  it can be used in XmlValidatingReader.ResolveEntity().
	  ResolveEntity() sets XmlTextReader.MaybeTextDecl.
