Hi Alex (cc to the list),
Your feedback was very helpful. And I've finally learnt more about XML Schema 1.1 validation, which is now available in the new snapshot [1]. I have also completely revised the documentation on our Validation Module [2].
Looking forward to your feedback on your first tests, Christian
