I think that if the three different namespaces happen be interchangable
for the purposes of YOUR process then it is YOUR responsibility to say
so. This implies that XSLT, Namespace-filters for SAX, DOM etc.need
extensions for stating that two namespaces are interchangable for a
given task. Yes, there should also be a way for a namespace creator to
globally state that a namespace is a subset of another namespace but the
lack of such a declaration cannot be blamed on the XHTML people. They
are trying to do the right thing.
