xpointer

This version correctly implements XPointer with the limitation that it can only process single-xpointer fragment ids and does not address any of the XPointer-specific extension functions (unless Saxon happens to implement those). It will report errors for fragment IDs that are not XPointers. I think this version is pretty stable--there's not much more functionality I can add to it.
