Actually so do I -- I meant to clarify this.

I was going by something Dan Connolly posted on XML-Dev that seemed to
read that way ... which I actually didn't agree with.  (I've not had
a chance to catch up to quite everything there, as I was off-net for a
week; and I might have misread it.)  If it were actually intended that
namespaces not work with validation, it needs to be explicitly stated.
(And then folk need to recover from the resulting firestorm ... :-)

What you said below, I certainly agree with.
