I have just downloaded the latest version of the protocol document to:
ftp://ftp.pwg.org/pub/pwg/ipp/new_PRO.
The documents are:
ipp-pro-980109.doc MS Word Version 6 with no revisions
ipp-pro-980109-rev.doc MS Word Version 6 with revisions
ipp-pro-980109.txt text with no revisions, same as
draft-ietf-ipp-protocol-05.txt submitted
to IETF today.
This is the version that will go to the IESG if we reject XML and
stay with the current protocol.
