That's how the policy was explained to us when we (and the xslt WG at
same time) got lumbered with dated URI's for our respective namespaces.

Ah that's a different policy.
Having a date in the URI does not imply it will change when a version
changes, that is definitely the case.

But conversely every W3C language is now requirred to state the policy
of when it does expect to change the namespace URI which can be
various things basically ranging from as often as possible to as
little as possible.

I disagree with your assement by the way. Changing namespaces is
changing every named construct in the language. ie it's not a new
version it is a completely different language. Sometimes the changes are
so radical that that is what you want, but usually it is not what you
want. This is the heart of the (in)famous three namespaces for XHTML
debate.
