I don't understand that.  You are saying that the decision 
to name the top level element is too constraining?

That's what I'd feared.

This seems a considerable flaw in XML Schema and by association WSDL.

To elaborate on why we wanted such a schema...

It's our practical observation that a loosely-coupled document based
web-service ought only apply constraints to enforce tight/tighter
coupling as necessary (typically production) but when possible the
constraints are best kept loose - this is particularly the case during
development, when data model and process may be in flux.

In other words the development philosophy is - create the
service/process and constrain after the fact as necessary.

It seems like XSD and WSDL approach the world with the opposite
philosophy mandating that a schema be developed before the service.
