somewhere else above and beyond this spec.

i think there may indeed be systems which accept EPRs from unknown parties 
and blindly send a reply, and that's fine.
 
*but* many async scenarios involve some out of band negotialtion before the 
messaging occurs. A sender may elect to only send messages to parties 
known and use configuration to decide upon the actual means of transport.
 
my company is keen to ensure that it's possible to build both styles of
architecture with this low-level component.
