XPointer has been extended to support external entities [1], though:

"Like [XSLT], XPointer allows the root node to have multiple child
elements, to allow XPointers to address into arbitrary external parsed
entities as well as well-formed documents."

I wonder what you can do with a set of nodes identified by a XPointer if
it has no infoset!
