I believe that there is wording in the Web Arch document that says that
namespace names may identify compatible versions of a space of names [1].
Does the WSDL spec talk about allowing or disallowing this kind of namespace
management policy?  Also, now is the time to comment on the web arch last
call if you disagree with this udnerstanding of ns names.
