Excellent list.

At least in my understanding #1 and #2 are equivalent, with #1 being any
Joe's description and #2 being a UNECE Recommendation, but they are both at
the same level. I would not call this 'business protocol', just because I'm
afraid that talking to a business person about rules of engagement and using
the term protocol I would be thrown out the window ;-)

Maybe a more appealing term like 'business use case'?

No #3 and no #4 seem to be at the same level. We usually refer to that as
'business scenario', basically an outline of what you are planning to do in
that particular business context. We usually describe that using very
abstract choreographies (no services included).

No #5 is really an implementation, but I would switch order and put the
interaction first (#6->#5) and then build an implementation to support it at
#6. Quite frankly, I would much rather use the term 'WS Choreography' to
describe that.

So where is the 'business protocol'? Maybe it's the mythical beast that
exists when one combines scenarios with actual communication, it's half way
between #4 and #5 and maybe both at the same time?
