mm1: Sally, I would caution that when you look at the high-level 
business entities that are referenced within UN/CEFACT and BCM, they may 
or may not be a legal entity in the context you have cited in our usage 
scenarios. And, they are several layers of technology, definition and 
interactions in between.  Shouldn't we be breaking these into constructs 
that are most relevant to and will exercise BPEL specifically not in 
general? Otherwise, BPEL may not be as concentrated on its area of 
expertise. My point is to stay focused on what BPEL can do well. Thanks.
