It sounds as though you could use @property with the same sort of intermediate dictionary that we think we can do for extensions to the repertory of values for @role. Here (If I have it straight) we will have a role dictionary (separate URI from the XHTML 2.0 namespace or the current document instance) which has a named entry which gathers a collection of assertions and then a qualified name referring to this named entry in the dictionary will assert those assertions about the element bearing that QName as a value of @role. In the process of developing this we will definitely need assistance from SW [Best Practices?] and would be delighted to compare notes with "the people who brought you NewsML." Keep in touch with Lisa or post progress updates or questions to <wai-xtech@w3.org> for public discussion and <w3c-wai-pf@w3.org> if W3C member-confidential for any reason.
