Creating Web Services element portlets with WSDL and older XML schema

[CR #329318] When you create a Web Services element portlet that uses WSDL with an older XML schema (for example, http://cvs.apache.org/viewcvs.cgi/*checkout*/xml-axis/java/test/wsdl/types/ComprehensiveTypes.wsdl), you receive an error message saying the schema is not supported. The error message looks similar to:

The following namespace "http://www.w3.org/1999/XMLSchema" is no longer supported.

Workaround: Update to the W3C XML schema recommendation at org.exolab.castor.xml.schema.reader.ComponentReader.error and org.exolab.castor.xml.schema.reader.SchemaUnmarshaller.handle Namespaces.
