If the rules only require simple logic (no back-tracking, complex 
chaining, etc), and if you are just wanting to identify documents with 
certain patterns, then Schematron is the simplest thing to use.

Proprietary rules language tend to use higher-order logics or have 
domain-specific capabilities; they need advanced features to justify a 
price. Schematron just uses XPath.
