  Actually XPointers are now context independant (you don't inherit
any namespace information from a possible XML embedding context).
  But the problem David pointed is still perfectly valid for the use of
QName attribute values, where you have really no way to know a-priori
if the content of the attribute is supposed to be a Qualified Name or
just any CDATA.
