Murata Makoto, Dongwon Lee, and Murali Mani. "Taxonomy of XML Schema
Languages using Formal Language Theory." in Conference Proceedings,
Extreme Markup Languages 2001, p. 153-166. (Abstract:
It examines DTD, W3C XML Schema, DSD, XDuce, RELAX Core, and TREX, not
Schematron per se, but I would expect Schematron to have expressive
powers in the RELAX/TREX zone, perhaps even more. Schematron is
intriguingly off the charts for a lot of this.
I'm not sure that article is presently available to the world (I have a
printed copy of the proceedings), but it's fascinating stuff.
