Clearly this is not acceptable.

The example I gave assumed that the same entity that produced the first
WSDL (and has access to the domain name used for the namespace) produced
the "versioned" WSDL. The way I understand versioning, this is the most
common scenario. Someone who defined an interface later decides to
update it with a new version.

I can see some senarios where the "new" interface is defined by someone
else, but at this point are we really talking about versioning or a more
general concept of compatibility. I think this is stretching the
definition of versioning. I would suggest (again) that people who need
support for expressing relationships between services, between
interfaces and between services and interfaces look into the work of the
OASIS WSDM TC instead of trying to get this out of WSDL 2.0.

In any case, if this was to be supported in WSDL, one could imagine a
URI creation rule that would make me create a URI that looks like
http://vambenepe.com/newVersionOfWSDL?base=http://www.markbaker.ca/my-se
rvice/namespace/&version=3/2/1/2. So the URI would be in my domain but
reference one in your domain.

In any case, in no way do I suggest that people can create URIs without
the agreement of the owner of the domain name used.

Regards,

William
