Harvey-
You really put a big effort into getting the presentation together for the full TC. Your docs have evolved a lot.
I disagree with some of the points made in the ppt. Specifically in Slide 5 does not answer the question by definition; and the use case subgroup's primary artifact production should be use cases, not bpel files. In Slide 7 I don't think we want to make use cases; ideally we would like to expropriate (steal/borrow/use) existing use cases that have applicability, and use appropriate business patterns even if they are in available repositories that are not associated with a known organization. The first point on Slide 7 I see in direct conflict with slide 8's "create fictional yet concrete instances of..." I disagree with the premise of slide 8. Not only does it imply engineering a result but it will require a lot of work that I think other people have already done.
