ok but we just agreed that XSD doesn't do the kind of validation that is needed by archetypes, so I think what you are really proposing is XML based on Relax NG as a sufficiently powerful approach that would a) implement the required constraint semantics of archetypes and b) create data that can be queried by Xpath/Xquery out of the box? Is that your suggestion? If so, my reaction would be: let's investigate as a community. I don't think anyone has sufficiently investigated Relax NG or Schematron for openEHR purposes, and in hindsight we probably should have. It would be very interesting indeed to see how much better it would work than XSD. I think if you make any progress in your work on these questions, let's turn them into specs / guidelines / whatever for general use in openEHR. - thomas
