Pointers, as well as new attributes:

 * xfrom: the extended pointer in the "from" attribute, as an XPointer

 * xto: the extended pointer in the "to" attribute, as an XPointer

 * xp: an XPointer including the range from the location specified in
   the "from" attribute, to the location specified in the "to"
   attribute.
