I have just downloaded the new version. The documents are
ftp://ftp.pwg.org/pub/pwg/ipp/new_MOD/ipp-model-1.2-rev.docftp://ftp.pwg.org/pub/pwg/ipp/new_MOD/ipp-model-1.2-rev.ps
The revision are against 1.0, though the ones since 1.1 are in a different
color. If you have MS Word you can uses the revision tool to produce
a diff of the two files.
The main things to look for:
the table of contents reflects the document, so it is a good place
to see the attribute organization.
some changes in the operations area.
a few new comments on adornments.
attributes rearranged and grouped according to previous discussions.
I forgot to put in an issue for printer-state which Tom and I discussed
but did not reach resolution.
