Agreed. But I think we need it in the shorter term :-) Over the last day
Eliot Kimber has spent a lot of time (thanks :-) helping to clear up some
of my ideas about addressing and linking. (I have been much concerned about
how to build software that is unambiguous). I believe I'm quoting Eliot
correctly in saying that it is impossible to implement Xpointer rigorously
until we agree on the abstract model of an XML document. I suspect we
don't, all, yet...
