No, it wasn't the parenthesis that I missed, but the
"and send it as text/html"; if they do that, and
don't tell the Validator in some other way that they
are really trying to validator XHTML, then indeed the
postulated outcomes could occur.  But the solution,
surely, is to tell the Validator that one is trying
to validate XHTML, not HTML ...
