I disagree.  A BPM engine, executing a BPSS specification of a process, can 
be tracking these states independently of any back end fulfilment 
applications/services.  In fact, I would venture to say that it SHOULD manage 
these states separately from any internal state management in the back end 
apps, since as Bob so aptly pointed out, they are at different levels of 
granularity.

Since BPSS "[forces states] into a machine-processable XML document", this 
is not hard to do in a BPM engine.  Basically all a BPM engine consists of is 
some XML parsing code, coupled with it's own persistent data store (DBMS 
perhaps) to track state for various collaborations/conversations.

As I had mentioned in a prior email, BPSS Business Transactions are 
considered atomic, and as such do not need any visibility of more detailed 
back end/private states...that should be transparent to the public side of the 
process implementation.
