This issue was originally reported by Khaled Noaman/Henry S. Thompson.

Resolve the issues associated with restricting types whose elements
include identity constraints.  Specifically, (1) the rule must changed
to state that the restricted type must have a superset rather than a
subset of identity constraints, (2) the term superset must be clearly
defined, and (3) there must be a way to redefine identity constraints
in the restricted type without causing duplicate name problems.

We agreed that we would like to see the proposal written down. The
minutes say "The description in the minutes may suffice as written
proposal; if not, HT will write it up.  Others to say if the minutes
are insufficient."
