I have downloaded the latest protocol document. It isn't correct with
regard to i18n because that is still in process.
But it should otherwise align with regard to the model document.
The documents are at:
ftp://ftp.pwg.org/pub/pwg/ipp/new_PRO.
The documents are:

ipp-pro-971014.doc MS Word V6 without revisions
