Hi Larry,

You're missing the point.  The content headers can be used 'over-the-wire'
for IPP operations, but 'document-format' is an ATTRIBUTE stored with Job
and Document objects (in most protocols, and in IPP in the future, when
we address Document objects).  We're not messing with the MIME types.
They're deficient (read RFC 2184 and RFC 2130 - the IESG says "ALL text
shall be tagged with character set AND language in ALL new protocols").

We do NOT propose to mess with MIME types.  But we have a concrete need
for a SINGLE attribute which carries PDL/charset/language for documents
(in IPP protocol and in the Job Mon MIB).

Sorry for the confusion of problem domain in my previous note.

I think it isn't a good idea to muck with the MIME format for
Content-Type or to restrict the available parameters, or to
add another parameter for "language-selection" which doesn't
exist in MIME. If you want to describe some content, use "content-"
headers in entirity, "content-type: blah", "content-language: blah",
"Content-MD5: blah" or whatever.

document-format-description := content-header
