Is the Rational Rose model that you are talking about the one that is
included with the OEP releases from Boeing?  I've looked at the Rose
model that comes with the 3.0 release of the OEP and I don't see what
you are referring too.  In the model I'm look at, most of the components
simply use the abstract BM__EventSink (of which there is only one
implementation - BM__UpdateEventSinkAdapter_T) for consuming events and
the UUEventSupplier for publishing events.  Is there some attribute or
association that I'm missing?
