PRIOR to Bob Herriot's latest proposal, ALL previous
texts of the 'mailto:' delivery method for IPP
Notifications have permitted the IPP Printer (or
other notification generator) to insert machine-readable
content at will - please read the documents.
There has never been any concensus to completely
remove the ability to send machine-readable with
'mailto:' and it's never been documented in any
version of the working spec.
Note that Adobe Acrobat Reader is NOT built by MS,
Netscape or any other browser manufacturer. It's
just a simple application reader utility. Among
other useful goals, the current IPP Open Source
Client activity could quite easily produce and
freely distribute (like Acrobat Reader) this app.
NOTHING at all has to be done by a browser
manufacturer to enable this - it's just a new
MIME type that is connected to a well-known app in
the end user's environment when the end user
installs the reader app.
By the way, QualDocs is going to very badly need
machine-readable IPP notifications over email or
it's never going to work gracefully to extend the
current IETF Internet Fax standards - they're all
based on email notifications.

The IPP Notification I-Ds will now go the IESG)
I find it quite discouraging to see that you continually side-step
the issue of the likely lack of available client-side software to
make this thing truly useful on a mass scale.
Who's going to provide the client-side software? Microsoft? Netscape?
Do you honestly believe this kind of capability is going to shoot
adreneline through these major infrastructure component companies
such that they're going to quickly add integrated support to their
Recall that a very early premise of using HTTP for IPP was the
significant expectation that Netscape would be there with the PWG,
side-by-side, such that Netscape's products would have integrated
support for IPP right in the browser. Well, that just didn't happen.
How is this situation any different? Do you expect a company like
Xerox or Sharp to bestow a free capability to the world to make the
feature usable? Perhaps you expect this capability to represent some
sort of "market builder" concept in which many companies will rush
several competing products to market?
The PWG always prided itself on being more business-oriented than
other pure standards organizations (eg, the IETF, with all due respect).
A standards effort is started because a concensus declares market
viability. Moreover, the effort is scoped so that resulting products
(free or otherwise) are developmentally possible within a reasonable
period of time. And, above all, there is a clear and present benefit
by delivering products that build on the standard.
I (and others) have repeatedly stated that this is NOT the case with
machine-readable notifications within email messages. Just because
you CAN do something doesn't mean you SHOULD. (Deja vu all over again.)
Please don't misunderstand me here. If someone wants to go off and
submit a paper to the IETF and publish UNDER HIS/HER/THEIR names as
an "Informational" protocol (or whatever the term that's used to
denote a private research project), I have absolutely no problem with
that (and, in fact, would encourage it).
What I (and others) do NOT want is yet another long, drawn-out standards
effort that gets fatter and Fatter and FATTER as time goes on, one that
sucks up precious cycles from the PWG membership.
And with that, I shall refrain from further responses on this subject
unless explicitly asked (or targeted).
PS: In spite of this discord, I hope you and Nancy are enjoying a fine
Grand Marais summer! I wish Nancy the best with her gardening efforts.
