Actually, I'm convinced that we'll never define equivalence, except on a
per-application basis. One of the things I've become convinced by from
looking at the problems of round-tripping XML documents through
databases is that there are *many* levels of equivalance. The infoset
and canonical XML are just two of those, and it's useful to have them
standardized, but many applications would hold that these have too much
detail and others that they have not enough.
