  XPointer id() is actually XPath id() and only works if you can assert
IDness of an attribute, and that requires a DTD per the spec. Trying to
make what you suggest would simply make the library not conformant to the
specifications. Sorry that's not possible. Use a different XPointer
expression not based on id().
