> The problem here seems to be that when message.xsd is imported in the WSDL file *and*
imported in another schema that is also imported in the WSDL file, the code generation process
does not realize that they are the same schema, thus leading it to believe that the type MessageContext_Type
is a duplicate global type when it is not.  I will attach an example that demonstrates the
problem clearly.
> This problem does NOT occur when XMLBeans 'scomp' is used as a standalone tool.
> Of particular interest is the behavior of the method baseURLForDoc() in org.apache.xmlbeans.impl.schema.StscImporter.
 When running scomp as a standalone utility, fully qualified absolute paths are passed into
this method, but when using WSDL2Java, relative paths are passed in.
