Not much of a problem, really, at least for SAX-style parsers that
return the GI and the attribute map at the same time.

But "xmlns" *begins* with the string "xml", which is what is
reserved.  *Any* name beginning with those three letters is
reserved, like "xml-foo" or "xml:bogus" or "xmlxml".

The trouble is that PIs don't nest within the element structure,
and the whole point of the new draft (IMHO) is to localize
prefix definitions so they are not just document-global.
