Semantics for BPEL4WS?

XLANG is based on Pi-calculus and WSFL had a petri net operational
semantics, I believe.  Has anyone at IBM, Microsoft or BEA defined a
semantics for BPEL4WS?  I didn't see it in the specs below.  If not,
are there plans to do this and if so, what can you tell us of this?

Thanks,
Sheila McIlraith
