    I'm a bit confused: I had the (apparently flawed) impression that the plan
    was to deprecate, for a client, using the "last-document" operation
    attribute entirely--that is, say the "correct" way to say a job was done
    was to do Close-Job. If we do that, we will by definition deprecate the
    special case you're discussing below, right? Am I thinking of PSI or maybe
    SM?

    Since deprecation is only a suggestion, might it make sense to deprecate
    "last-document" entirely? (The Printer will still have to support it, but
    we're encouraging clients to move to Close-Job.) Do we want to make such a
    stand?

    In going over my notes I discovered one more significant conformance
    changes
    proposed change for the IPP Document object from Thursday's April 17,
    telecon. This proposal will also go through the two-week comment period.

    1. DEPRECATE the way a client can close a Job by supplying an empty
    Send-Document operation supplying the "last-document" = 'true' operation
    attribute for a Job created with Create-Job and any of (1)
    Create-Document/Send-Data, (2) Send-Document, and/or (3) Send-URI. When
    the
    Printer accepts this no-data Send-Document operation with "last-document"
    =
    'true' the Printer MUST set the still REQUIRED "last-document" Document
    Description attribute. Instead, the client SHOULD use the new Close-Job
    operation (which also sets the "last-document" Document Description
    attribute).

    The Printer MUST continue to support this method of closing a job with an
    empty Send-Document request for backward compatibility with existing
    clients.

    As with the other two mail messages on significant conformance requirements
    changes, I will not edit this comment into the spec until we reach
    consensus
    on Friday, May 1.

    Please send comments.

    Tom
