Hmm, I hope it's not getting to philosophical now ;-)  I'm sure it's no longer
related to Stéphane's original question, but nevertheless let me ask: Wouldn't
it, in some cases, be reasonable to make XML namespace URIs usable as
vocabulary URIs?  What URI would, e.g., the xhtml:h1 element have if you
wanted to talk about it in RDF like …

    a :XHTMLElement ;
    :content :text ;
    ... .

OK, so far, this is just a reinvention of any XML schema language in RDF, but
I could well imagine that there are reasonable use cases for attaching
_additional_ information to an XML schema using RDF.  But as XML namespace
URIs don't end in / nor #, this would be impossible, or, at least, not nice.
