    All,

    Here are the issues I am currently aware of regarding v0.95 of the PWG
    Schema. If you have any comments on one of these issues please cut and
    paste the issue into a new mail note with a subject line of "Schema Issue #"
    where # is the number of the issue from the list below
    Thanks,
    Pete

    1) ProcessingActual.xsd has a duplicate definition of OutputBinActual
    in JobProcessingActual - I pulled it out and it was fine in sqc
                                    <PZ>Duplicate was supposed to be
    "OutputDeciceActual". Fixed in all sub-schemas.</PZ>
    2) the PWG SM schemas liberally use <xs:any namespace="##any"/>. The
    sqc apparently dislikes using ##any for the namepace wildcard if the xs:any
    is in a sequence with any other elements. If I switch this to <xs:any
    namespace="##other"/>, the problem goes away. I couldn't find any
    documentation on why this is a problem, but the sqc doesn't like it.
    Interestingly, it looks like you can add !both! <xs:any
    namespace="##other"/> and <xs:any namespace="##local"/> and it works fine -
    which in theory is the equivalent of <xs:any namespace="##any"/>. I did
    find this pattern in a sample online, but I haven't yet found any
    description on why <xs:any namespace="##any"/> is a real problem. It does,
    however, fail the sqc, and we think it may be what is causing some of the MS
    tools to give up on the SM schemas as well
                                    <PZ>Actually the replacement for <xs:any
    namespace="##any"/> would be <xs:any
    namespace="http://www.pwg.org/schemas/sm/latest/"/> and <xs:any
    namespace="##other"/>. We do NOT want locally defined elements. All
    extensions MUST be fully qualified with the namespace to federate extensions
    to the schema. In all examples I have seen from the W3C they use '##any"
    for this type of extensibility. I still have not reinstalled all my XML
    tools yet or have not had time to try them on this issue. It seems to me
    that '##any' is exactly what we mean.</PZ>
    3) The PWG copyright on the schemas still says 2002. I'm assuming we
    need to roll this to 2003.
                                    <PZ>Added ", 2003" to copyright notices</PZ>
    4) "JobPriority" need minimum value of '1' and maximum value of '100'.
                                    <PZ>Added to "JobPriority" and
    "JobPriorityDefault"</PZ>
    5) The "MediaSizeSelfDescribingNameWKV" element has an enumberation
    'om_large-photo_200x300' that should be 'om_large-photo_200x300mm'.
                                    <PZ>Fixed</PZ>
    6) "DocumentFormatWKV" needs 'application/vnd.pwg-xhtml-print+xml' and
    image MIME types
                                    <PZ>Added
    'application/vnd.pwg-xhtml-print+xml', image/g3fax', 'image/jpeg',
    'imag/tiff'and 'image/tiff-fx'.</PZ>
    7) "DocumentFormat" does not allow certain extension values.
                                    <PZ>The "MimeExtentionPattern" SimpleType is
    not correct. As a quick fix I changed it to have a value of
    '(\i|\d|\.)*&#x002F;(\i|\d|\.\p{P})*'. I have not tested it yet. Anyone
    with time to create a proper pattern describing MIME would be
    appreciated.</PZ>
    8) "PrinterStateReasons" should include the values 'AttentionRequired'
    and 'MarkerFailure'.
                                    <PZ>Added them</PZ>
    9) "DocumentFormat" need the value 'unknown'.
                                    <PZ>Added it</PZ>
    10) "JobAccountingId" should be "JobAccountingID".
                                    <PZ>Fixed</PZ>
