Re: [soa-rm] On POAs and SOAs

[Matthew MacKenzie <mattm@adobe.com>]

It strikes me that POA is really something that sits on top of the SOA 
paradigm, and in the case of compound services composed using process 
management tooling, acts in a service composition capacity.  As a 
result, I'm not yet in agreement that POA needs to be referenced 
explicitly within the RM.

In other words, there are synergies, but not dependencies between the 
two.
