	* DTDObjectModel.cs : (DTDAttributeDefinition) create ArrayList
	  only when they are required.
	* DTDReader.cs,
	  XmlParserInput.cs : raw tag string now don't have to be kept, while
	  it cost so much. Removed unused code. 20% to 30% memory got saved.
	* XmlNotation.cs : removed unused code.
	* XmlTextReader.cs : Removed unused code. ReadString() now uses
	  XmlReader's internal method. Fixed BaseURI to be conformant with
	  W3C XML InfoSet and (subsequently) xml:base specification (i.e.
	  reflect xml:base attribute correctly).
