The Schema WG has formed a small task force which is preparing a
recommendation on how the Schema specs should address "better reference
mechanisms" [1].  Among other things, they will be addressing scoped IDs
(document-level, GI-level, archetype-level?, XPath-level?, etc.) as well as
IDREFS (or other mechanisms) for referencing such scoped IDs.

A summary of the task force's recommendation and technical discussion of
that recommendation will take place on the Schema IG list [2].
