Hi,
We're going to eliminate the hole! Nobody really wants to keep it.
Bert said that IETF WGs sometimes moved around OIDs in Internet-Drafts
(working documents). We've already moved around the OIDs at LEAST
three times in our working documents and we're going to do it once
more and quit, because we agree that we've got all the necessary
objects.
Bert - none of these working documents has EVER been approved or
promised ANY stability of OIDs.
Cheers,
- Ira
PS - As I promised Jerry Thrasher earlier today, new ASN.1 by
end-of-day tomorrow (Friday) or sooner if I can.
PPS - Jerry or Mike still needs to incorporate the rewritten
Requirements section into the right place in the boilerplate.
PPPS - And I need to write edits for Internationalization and
Security sections, because we moved some elements up (logically)
from the previous ppmPortTable to the new ppmPrinterTable.
