UML22 — Federated models - UML2 issue

When creating a complete environment for agreements and BCF we need
to
work with ModelElements, classes, package, models etc created and
managed by many unrelated person and organisations. This means that
we
need to support loosely coupled models (federated models) where an
association starts in one model (stored in doc A) and ends in another
model (stored in document B).

This may mean that we need to add references to an external
modelelement
so the assoication that references "out" to external ME need to be
annotated with for example UUID of remote modelelement, name of model
where the remote/external model , physicial location of remote model
(URL) etc.
We may also want to attach constraints to the remote modelement that
restricts "incomming" associations.

The question is how are loosely coupled model handled in UML 2 ?
