Thanks - I'll be reading this on the train home (in ten minutes).


How far do orchestration languages like XLANG and WSFL address your 
concern about composability? If I understand REST aesthetics at all, I 
guess that a REST approach would favour bottom-up (each service tells 
you about its acceptable successors) openness over top-down (you get the 
whole map pre-written) completeness.

Never underestimate the power of emergent properties....
