Hi,
I agree with Dave Whitehead that required document formats (or any other
new IPP requirements) belong in a separate standards-track PWG spec.
Prototyping in the PWG Process does NOT require any interoperability testing
at all. It's just a partial implementation (no minimum content) by a
single vendor.
Interoperability testing (AFTER approval of specs) is also part of the PWG
Process but is NOT required to bring a document to Formal Approval vote
as a Candidate Standard (unlike IETF and many other standards bodies).
For IPP2x versions, a prototype could be one printer in a lab with a
test client.
I also agree that prototyping *some* required IPP document formats could
be trivially accomplished.
If we need new IPP projects, then so be it. But please let's not destroy the
chance of IPP2x by introducing new content and breaking the concensus
to proceed that was based on no new content.
IPP/1.0 implementations DO NOT conform to IPP/1.1 and WILL NOT conform
to IPP/2.0 - end of story.
Cheers,
- Ira
