I have created schema based on version 0.33 of spec and other discussions to the best of my recollection.. Alan - I think we need to update the DFDL property description for Any element (page 130) . The document is missing DFDL properties for ALL group, In the schema I have assumed ALL group to have the same set of properties as the Sequence group. It is quite possible that I might have missed some property or had a typo in the property name. We should schedule review of the schema next week. As you would notice in the instance documents, the attribute instances in the special annotations are unqualified as per the spec.. Also there is a global attribute definition for each of the DFDL property defined in the spec..
