Not really,  could be 1 second.  My point is that a commitment
only makes sense for economc events that have not happened.  
Economic events can also happen without prior commitments,
of course.

It might help to reiterate what REA means by economic events:
only actual increments and decrements of economic resources,
that is, consumption, production or transfer of ownership.
Messages that send purchase orders, for example, are
commitments in the REA ontology, not economic events.

Good, I'll look for it.  I am on the road for a couple of days,
and so will not reply again until the weekend.

I agree.

I don't understand that perspective.  Maybe we just need to agree
to disagree on this point, and see how it works out as ebXML

I think we are in agreement here.

Thanks again,
