That all depends to whom one is trying to explain WSA to. I don't claim 
its the only diagram you need.

On the other hand, if a bunch of smart people can get confused over the 
triangle diagram, guess how the rest of the world will feel?

I would start to explain SOA by addressing the different kinds of 
things are of concern. Perhaps a bottom-up approach is easier for 
technologists to get their teeth into; but knowing where you are going 
is also useful.

I.e., something like the following:

The heart of WSA is enabling two computer systems to fulfill their 
roles in a common task; be it purchasing a book or logging an expenses 
report, or whatever.

In order for that to happen the parties must find each other.

To support larger-scale interactions it must be clear -- to a computer 
-- what the roles, rights and expectations of the parties are.

In order for the transaction to be valid it must be clear whom is doing 
what to whom; and why.

And so on.

I guess that, in this scenario, I wouldn't be over-emphasising 
individual MEPs but more staking out the territory the WSA covers. Then 
you go in and `fill-in'.

I would observe here, that the WSA WG's remit in `filling-in' is 
somewhat fuzzy: we don't do SOAP itself, we don't do descriptions 
themselves, we won't be doing choreography itself, etc. etc. We MUST 
try to get that global POV that helps the other groups relate to each 
other and to Web Services as a whole.
