I don't think it is a hack. I just don't see it as a fully described
algorithm. The devil is in the details.

At least two of the schema working group members are knowledtable about
forest automata theory but that group is being asked to do a hell of a lot
of stuff from people with widely varying backgrounds. Nobody has time to
do all of the appropriate "homework."

Well forest proponents are not a team or a political party. Murata-san has
shown how forest automata can be used to develop schemas that are context
sensitive. I don't think anyone has implemented a full schema-evolution
solution.
