I’ve had quite a few reports this week of organizations using Schematron. The latest is that the UK police use it to validate all the criminal records from 46 different forces, according to a post on the maillist. We are just starting to see the use of Schematron by standards committees, who are probably basking in the naughtiness of using RELAX NG...

...For example, you could use Schematron abstract patterns to say “A conforming document must have at least 4 Dublin Core metadata elements”, then have instances of that abstract pattern to cope with ODF, Office Open XML, and XHTML.

Schematron is the only XML schema language I am aware of that has a built-in idea of schemas for information independent of the representation (abstract patterns). As XML becomes ubiquitous, and whenever standards efforts faulter due to commercial rivalries and differences of vision, there will be a need for validation of the information requirements independent of the structure...
