Pardon me for rearranging the order of your comment, Gene, but I wish to
emphasize that your point above is preeminent. I strongly agree.
Having said that, it is with a certain apprehension that I attempt a
response to the rest. Discussions on cultural differences among standards
groups often reach a speedier conclusion in face-to-face meetings than they
do in the medium of EMail.

I think the distinction between a "follow-on" vs. a "revision" standard is
cultural and likely a distinction without much of a difference.
For example, products compliant with IEEE Std 1394-1995 do not have a
problem with the advent of IEEE Std 1394a-2000, nor will they have a
problem with the eventual advent of IEEE Std 1394-200X in some future year.
The pertinent standard does not cease to exist with the publication of
revised or follow-on efforts.
Many standards bodies follow this model. Which is not to say that others
are right and T10 is wrong; it is just to point out that this is not a
truly substantive matter that impinges upon the utility of the standards in
At this point I could present my own opinions on the naming and numbering
of standards, SBP in this case, but I sincerely believe that the dialog
will be more compact if conducted in person instead of over the reflector.
