Re: [soa-rm] When Is An SOA Really An SOA?

Joseph:

This is a key aspect of why we are doing this exercise.  We have a 
section (placeholder) called conformance but at this point it is not 
clear if we could (or should) make a blanket statement.  At the face to 
face, the thinking was more in tune with what it would mean if someone 
stated their SOA was conformant with the SOA RM.
