Modified Files:
 	XMLSchema.py -- there was a indexing logic error in Restriction/Extention
		classes fromDom method.  Also changed the attribute dictionary of all
                classes that inherit XMLSchemaComponent, now all attributes
		are organized by namespace.

 ----------------------------------------------------------------------

Modified Files:
 	XMLSchema.py --
            Wasn't resolving schema imports in every scenario.
            Now look in parent schema imported_schemas first, second look
            in the parent wsdl, lastly try to resolve schemaLocation.

            Removed 'what' parameter from marker interface methods, I don't
            know what it was doing there.  Check self.

 ----------------------------------------------------------------------

Modified Files:
 	XMLSchema.py -- changed getQNameAttribute to return None if it
		can't find QName obj in it's own tns or in any of its
		imported namespaces.  Used to throw an exception.

 ----------------------------------------------------------------------

Modified Files:
 	XMLSchema.py -- fixed some default attribute handling, added a
		few get methods in XMLSchema for elementFormDefault,
		attributeFormDefault, blockDefault, finalDefault.  Also
		added a global method GetSchema.  Now default attributes
		are set correctly in all schema components.

 ----------------------------------------------------------------------

Modified Files:
 	XMLSchema.py -- checking for wrong class in two methods.

 ----------------------------------------------------------------------

Modified Files:
 	XMLSchema.py -- removed bogus method setType in SimpleType class.

 ----------------------------------------------------------------------

Modified Files:
 	Utility.py -- Added a parameter to Collection class constructor,
		'name' is the default attribute used for keys but one
                 can specify whatever key they want.

        XMLSchema.py -- Used the above parameter to make Collection
		instances use the appropriate 'attribute' as key.

 ----------------------------------------------------------------------

Modified Files:
 	XMLSchema.py -- still a couple mistakes in constructors, changed
		XSDNS to SCHEMA.XSD_LIST which was a mistake.

Modified Files:
 	XMLSchema.py -- missing parent parameter to a few constructors
		that expect to see it.  fixed.

Modified Files:
 	XMLSchema.py -- added LBNL copyright header.
 Added Files:
 	license.txt -- LBNL copyright.

Modified Files:
 	XMLSchema.py -- fixed a couple bad variable references.

WSDLTools.py -- just a few minor changes so the new schema class
		will be used instead of the schema tns placeholder.

		Might want to add an argument to WSDL.load method so that
                programmer can specify the placeholder or actual
		implementation.

        XMLSchema.py -- mostly new, unused original code is commented out at the bottom.

XMLSchema.py

 ----------------------------------------------------------------------
   fixed an obvious bug, added a SchemaError class so it can actually
be thrown.
