I'm not sure the semantics of the PCN information -- particularly as it 
relates to flow termination -- are correct without some sort of concept 
of aggregation. Or can you really define an RSVP object that has 
semantics "Never mind the SESSION in this message, I'm related to every 
flow with the same first hop"?
