[Mono-list] Xml Schema Update

[Dwivedi , Ajay Kumar]

Hi all,
	I have updated the System.Xml.Schema namespace in the CVS. The
latest functionality is almost full support for Reading schema files to
create a SOM. The method checks for well formedness and ordering of elements
in the schema. Most of the validations which are possible during reading the
schema are being done.
The following are the comparision stats between mono & MS implementations,
after Read() method on 4806 test files
	Total tests = 4806
	Same as MS failed = 662
	Same as MS passed = 4144
	Only MS failed = 0
	Only MS passed = 0

And after the Compile() method is called, the stats are 
	Total tests = 4806
	Same as MS failed = 1108
	Same as MS passed = 2494
	Only MS failed = 328
	Only MS passed = 876

	So, A lot more to go.

Happy Hacking,
Ajay
