The Schematron is an innovative schema language for XML documents radically different from existing approaches. It can be used as a friendly validation language and for automatically generating external annotation (links, RDF, perhaps Topic Maps). Because it uses paths rather than grammars, it can be used to assert many constraints that cannot be expressed by DTDs or XML Schemas.
