	* XmlDocument.cs : Load(string filename) should close its stream.
	  Small change for the latest DTDObjectModel change.
	* XmlTextReader.cs : Changed for the latest DTDObjectModel change (all
	  changed methods are only related to DTD stuff).
	  Now uses XmlSchemaDatatype for attribute type definition.
	* XmlValidatingReader : initial (limited) support for DTD validation.
	  It can handle only XmlTextReader.
	* DTDObjectModel.cs : changed radically for initial validation support.
	* added DTDAutomata.cs and DTDValidatingReader.cs.
