Indeed. But the functions can't just globally map prefixes to URIs and back, as with the previous draft. They have to have an indication, explicit or implicit, of context as well. In the DOM world, a DOM Node; in the SAX world, it would be necessary to only call the functions between the declaring elementStart and the corresponding elementEnd. Otherwise, there would be no assurance that the relevant mapping would still be correct. > I suspect there will be a similar issue with XPointers.

So I believed too, but someone on this list pointed out that because XPointers aren't queries into unknown documents, but references into known ones, the "foo:" might be the referent's "foo:" prefix rather than the referer's.
