xlink: is only allowed because of legacy usage (and only in "foreign
content" ie mathml or svg) I would think there is next to no possibility
of adding more namespace support to html with its current working group,
although someone is welcome to try:-)

However it would be pretty odd to use xhtml-namespaced attributes in an
xhtml context anyway so I don't think we should ask for that. The
request to allow namespaced attributes was (as far as I understand it)
to allow rdfa to be used with other unrelated markup languages that
might otherwise have clashing attribute names.
