I think it's easy to misread what Henry's saying here.  The actual 
"xml:" namespace URI is http://www.w3.org/XML/1998/namespace (see
http://www.w3.org/TR/REC-xml-names/#nsc-NSDeclared) if you deref that
you find a helpful human-readable document.  A couple of suggestions:

- that document might also usefully include a pointer *into* XML-names,
  http://www.w3.org/TR/REC-xml-names/#nsc-NSDeclared
  where the actual URI is specified, it can be a bit tedious to track
  down by hand.
- it should also have pointers to Henry's .xsd documents (and any other
  available schema-ware; for example the latest rev of the
  language-tagging stuff).

This seems a bit on the fuzzy side... there's room for argument around
the notion of "well-known"-ness.  Do you mean "all those defined in
W3C recommendations?"  -Tim
