I disagree: It is absolutely possible with WSDL 1.1.

Why is it hard to implement? 

It *is* a continue to support a feature as well, but I was suggesting
that we consider it on its own merits. However, if it'll help folks
then its fine with me to consider it that way.

Me neither and I doubt anyone else is either.

I disagree.

Note that one CAN have multiple WSDL documents for the same
targetNamespace. That's a fundamental design feature of namespaces
that we aren't about to walk away from .. so I don't understand
the comment "required uniqueness of namespaces."

I don't like to accept arguments based on something in the schema;
the schema should be written to support the language, not the
language to support the schema.

Do you agree with my scenario? Do you believe its ok to force
people to put Java classes into different Java packages as I 
described? The WSDL case is similar.

Sure, clarification is good, no matter which way decisions
are made.
