RE: invalid type error?

Playing with this further, if I generate java classes for the schema (using
scomp), then the document is validated without errors.

So, I am guessing this means that validation via the generic XmlObject is
not supported even though the xml document specifies a schema?  Validation
is only supported in the generated classes?

Thanks,
