johnS:
Sounds good. And, as I said, I think Russ's arguments were sound
and we are in agreement.

johnS:
I would say more pragmatic - for ease of adoption. Although if unlimited
recursion (which Russ called "ad nauseum") were fundamentally prohibited,
I don't think you would be severely restricting the usefulness of the
transaction based interfacing use model either.

johnS:
OK, that's good input. So perhaps we can focus more on the analysis
requirements in the next meeting. It is one of the items on Damian's
discussion list.
