Without scaring anyone who doesn't really care about these things :) -- 

The issue is, in significant part, whether a namespace can have a one to
one mapping, or even a one to many mapping, to a schema, DTD, or other
defining mechanism, through the namespace URI. 

The XML Namespaces rec states that "it is not a goal" that such mapping be
possible. It does not, however, say it must not occur (spec language for
"you can't do that!"). 

Current XML Schema working drafts, do indeed include language that provides
for such mapping. It is a hotly debated point in that Working Group right now. 

That, combined with our group's general design philosophy, lead to the
choice of 3 namespaces, one for each "flavor" of XHTML (which are Strict,
Transitional, and Frameset , as were in HTML 4.0). At one point, we were
argued back to a single XHTML namespace, but we reversed ourselves on that
decision as the document went to PR. 

FTR: Tim Berners-Lee himself is a staunch supporter of the ability to map
namespaces to schemas. Even though the idea isn't universally popular, it
is highly practical, which should win-out in the end.
