mm1: First (politely), they would reference the latest specifications. 
We're almost ready to publish the v2.0.1 for Public Review for OASIS 
Committee Draft consideration.  ebBP (aka BPSS) is most suited for a 
monitoring engine that could understands the expectations, quality of 
service, choreography, constraints, logicsl business documents, 
activities, etc. described in the ebBP process definition.  Since the 
v2.0 and now v2.0.1 are very new, we're starting to see development of 
ebBP conformant process definitions. We know of several user communities 
and vendors that may implement these specifications and associated 
schemas (similar to other new technologies). It has been discussed that 
there could be a transformation of one party's view (and 1 or more BSI) 
into WS-BPEL (1 or more abstract processes and then executable). 
However, there is an important difference. ebBP and collaboration are 
peer-to-peer. WS-BPEL concentrates on centralized control 
(orchestration). Therefore, it, hypothetically speaking, could serve to 
help manage other enterprise application processes that support
Business Collaborations. We've recognized that several implementation 
options exist and we don't dictate which option is selected (For 
example, how tightly or loosely coupled the enterprise or collaborative 
processes are, or even if they are related).  Feel free to shoot 
questions to ebxml-dev, Dale Moberg, and myself. We'd be happy to try to 
answer your questions further. What is your interest? Thanks.
