I think that would be a bad idea, as I think you are, for the same
reason as the QNames in attribute context we've heard so many times
before from me.

Off the top of my head I would suggest a namespace handler object that
exists on the object, and if the stylesheet language of the document
is css it's pre-filled with the namespace's from css.  This allows us
to have simple use for the CSS case whilst still supporting the
flexibility to add namespaces later.  but that's very much off the top
of my head.
