We reviewed the PWG document entitled: IPP Exceptions Model for Documents
and Pages" at the meeting last week. One of the changes was to change the
term from "Exception Model" to "Override Attributes", since the client is
supplying Job Template attributes at the document level to override the job
level ones and/or at the page level to override the job level and document
level ones.
The -rev version shows all the changes from the May 8, 2000 version, except
for the 200 replacements of "Exception" with "Override". The files are at:

We agreed to keep this a PWG document and make it a PWG standard, since the
main use is in Production Printing and the IETF doesn't offer any expertise
in this area to us. It will be sent out for PWG Last Call soon.
Please send any comments to the pwg-ipp@pwg.org DL (but NOT to the
ipp@pwg.org DL). I'm only announcing new documents to both lists. If you
are interested in this subject, but are not subscribed to the
pwg-ipp@pwg.org, you may do so by sending "subscribe pwg-ipp" in the body of
a message to major-domo@pwg.org.
The Abstract is:
This document specifies an extension to the Internet Printing Protocol/1.0
(IPP) [RFC2565, RFC2566] and IPP/1.1 [ipp-mod, ipp-pro]. This extension
relaxes the restriction that each attribute value is the same for all pages,
all documents and all document copies within a job. For example, with this
extension, page 1 of a job could have a different media from the other pages
in the job or document 2 of a job could be stapled while the other documents
of the job are not. As another example, the first ten copies of a document
could be printed on letter paper and stapled while the eleventh copy of the
same document could be printed on transparencies with no staple.
This extension supports document overrides and page overrides by adding two
new Job Template attributes: "document-overrides" and "page-overrides" --
both have a syntax type of "1setOf collection". Each 'collection' value for
"document-overrides" contains an attribute that identifies the overridden
documents, namely "input-documents" or "output-documents". The 'collection'
value also contains one or more attributes that are overrides for the
identified documents, e.g. "document-format", "finishings", and "media".
Each 'collection' value for "page-overrides" contains two attributes that
identify the overridden pages, namely "input-documents" or
"output-documents" plus "pages". The 'collection' value also contains one or
more attributes that are overrides for the identified pages, e.g. "sides"
and "media". When the overrides apply to some but not all document copies,
the 'collection' value for "document-overrides" or "page-overrides" contains
the attribute of "document-copies".
This extension also supports subset finishing by adding a new Job Template
attribute "pages-per-subset", which specifies the number of pages per
subset. The extension allows finishing and other document attributes to be
applied to such subsets of pages.
