I think we need to look at an addendum to c14n, defining type-aware
c14n, which at least rewrites prefixes in known QName values, and
possibly canonicalises all simple values (e.g (decimal)0000.1000 -> 0.1).
This won't fix XPaths, but will cover many simpler cases, including
RDF (once it gets a sensible transfer syntax :-).
