RELAX-NG is getting good buzz these days not because it's based on the
formalism(s) of hedge automata and tree regular expressions, but because
it's elegant -- simple yet powerful. RELAX/TREX  are elegant because Makoto
Murata and James Clark very deeply understand both the underlying formalism
and XML itself. No amount of post-hoc formalism can create elegance when it
does not exist in the core of a design.
