	In a Business Process Modelling way, this would correspond
	to the logic evaluating the transition to a new state.

Yes - an economic element of the collaboration changes its state,
and that may also be a signal to an EAI software layer to send
something to the internal business app.

	I am not sure I am buying it completely.

	I would like to have this, though (as written in my paper)

My focus here is recognition of economic events
from legal and accounting viewpoints.  For example,
when ownership of an economic resource changes hands
is part of the public logic of the collaboration.  Likewise
the rules for when contractual agreements have been
formed.  So it's not like the collaboration software
decides to bother the legacy system, it's more like
some EAI layer can use these recognition events
as hooks.  

Jamie Clark of the ABA will have a lunch-and-learn in
Vancouver about legal ramifications of ebXML business
collaborations.  I plan to attend and take notes.
