Scott & Vinu, Thanks for your careful review and commentary on BIRD 119! Knowing how fine some of the technical points can be (and how tough it is to make sure that everyone is using the same terms in the same context), I think these items are best suited to a real-time discussion, instead of [what I expect would be] a very long email thread. I'm guessing that most people already have enough mail in their Inbox, and what matters is that the final spec is as complete and clear as possible. I recommend we take these issues up in the IBIS-ATM meeting on Tuesdays, and incorporate clarifications or enhancements into an updated copy of the BIRD. Todd. ________________________ Todd Westerhoff VP, Software Products SiSoft 6 Clock Tower Place, Suite 250 Maynard, MA 01754 (978) 461-0449 x24 twesterh@xxxxxxxxxx www.sisoft.com _____
