Modified Files:
 	WSDLTools.py -- added a line in Reader to to set WSDL.location
           for files so that imports with relative paths will work for
           file paths as well as urls.

        XMLSchema.py -- a couple Attribute fixes, and the WSDLAdapter
           wasn't passing it's parent into the XMLSchemaComponent
	   constructor which was messing up import lookups.
