Hmmm, seems like I might be the only person not entirely in favor. I'm
just not sure about spinning a new version just to collect specs together.
Would 1.2 have any additional conformance requirements? Are we going to
make OPTIONAL extensions REQUIRED now?
If there are no additional conformance requirements, then a printer that
claims to be IPP/1.1 compliant will be automatically IPP/1.2 compliant,
right? In fact, a printer that *was* claiming "IPP/1.1 and PWG 5100.3
compliant" would now simply be "IPP/1.2 compliant".
I guess I'm looking for a better justification for IPP/1.2. New
conformance requirements to create a "better" protocol would be a good
justification, I believe--are people thinking in this direction (for
example, should we make the Document object REQUIRED in 1.2?)? Causing
companies to implement extensions so that interop can be performed is
another good justification (if we believe that creating a 1.2 will have the
effect of creating additional implementations).
In short, what is our goal for IPP/1.2?

All,
I think an IPP v1.2 would be a good idea. It would give us an opportunity
to collect all the extensions into a single document. (A one stop shop for
IPP as opposed to about 1500 pages spread over some 28 documents) This
would also give us an opportunity for another Bake-Off. We have done a
very
good job on interoperability on the core specs. I am unsure about the
level
interoperability of the various extensions. I know some problems already
exist.

Hi,
Dennis Carney (IBM) recently observed that the IPP Document Object
spec was starting to sound a lot like "IPP/1.2". Below, Michael
Sweet (CUPS) again raises the possibility of an "IPP.1.2".
Is this a worthwhile idea?
_If_ there was at least one other editor who was MS Word literate
(Dennis Carney, Tom Hastings, ...?), I would volunteer to collaborate
on writing an "IPP/1.2" spec with new significantly higher REQUIRED
features that consisted entirely (or almost entirely) of pointers to
the definitions of operations, objects, and attributes in the over 30
documents (IETF and IEEE/ISTO) that currently specify parts of IPP.
Any takers?
Cheers,
