I’ve started writing a Schematron ruleset that can be used to validate your own XCRI-CAP document so that you can get something that looks like this.
You can grab my work so far from google code. So far the ruleset only checks the core elements but I intend to work on it further soon. If your new to schematron you I recommend a scan of the schematron site and should be able to work out what to do with the ruleset by following the instructions on an old post of mine.
If anybody feels the urge to update or improve the ruleset please feel free too 🙂
