    Hi folks, Saturday (23 September 2006)

    I've just posted a second draft of the PWG IPP Printer State Extensions
    (PSX) specification on the PWG FTP server at:

        ftp://ftp.pwg.org/pub/pwg/ipp/wd/wd-ippstate10-20060923.htm
        ftp://ftp.pwg.org/pub/pwg/ipp/wd/wd-ippstate10-20060923.pdf

    This draft is a major rewrite to capture the recent IPP WG concensus on
    design alternatives:

    (a) New values for the "printer-state-reasons" attribute for device
        alerts already defined in the 'PrtAlertCodeTC' textual convention;

    (b) New values for both the "printer-state-reasons" attribute and the
        'PrtAlertCodeTC' textual convention for finishing subunit alerts;

    (c) New attribute "printer-alert (1setOf octetString(MAX))" - to encode
        all the machine-readable columnar objects from 'prtAlertTable';

    (d) New attribute "printer-alert-description (1setOf text(MAX))" - to
        encode the localized 'prtAlertDescription' columnar object.

    For immediate review, comment on the IPP WG mailing list (ipp@pwg.org),
    and discussion at next IPP WG Telecon on Thursday 28 September 11am EDT.

    Cheers,
    - Ira

      Agent', and 'Printer MIB Client' protocol roles to section 2.2
