    Hi Pete,
     
    Norbert's found a bug here in the SM schema spec for
    custom media size. You probably already know, but
    I wanted to document it on the SM mailing list.
     
    Cheers,
    - Ira

    Ira,

    FYI...

    Norbert was looking at the extension pattern in the Semantic Model
    Schema...and yes there's a bug there.....

    Hi Jerry,

    I agree with you that I don't see the problem that Norbert's talking about
    in the ABNF - it looks fine to me - it certainly does NOT allow multiple
    periods in the fraction part.

    I agree that the spec should NOT point at that bogus location for the
    normative ABNF.

    We don't really have any firm ideas what to do with normative adjuncts
    (like ABNF or WSDL or whatever) to PWG standards-track specs.
    But they certainly do NOT belong in 'Candidates'.

    Cheers,
    - Ira

    Harry, Ira,

    I'm not an ABNF expert by any means but I don't see the problem in the spec.
    that Norbert is talking about. It looks to me
    like both the short-dim and long-dim specifications are exactly the
    same...???

    Here's the text from the MSN Specification:

    media-size-self-describing-name =

    ( class-in "_" size-name "_" short-dim "x" long-dim "in" ) |

    ( class-mm "_" size-name "_" short-dim "x" long-dim "mm" )

    class-in = "custom" | "na" | "asme" | "roc" | "oe"

    class-mm = "custom" | "iso" | "jis" | "jpn" | "prc" | "om"

    size-name = ( lowalpha | digit ) *( lowalpha | digit | "-" )

    short-dim = dim

    long-dim = dim

    dim = integer-part [fraction-part] | "0" fraction-part

    integer-part = non-zero-digit *digit

    fraction-part = "." *digit non-zero-digit

    lowalpha = "a" | "b" | "c" | "d" | "e" | "f" | "g" | "h" | "i" |
    "j" | "k" | "l" | "m" | "n" | "o" | "p" | "q" | "r" |
    "s" | "t" | "u" | "v" | "w" | "x" | "y" | "z"

    non-zero-digit = "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"

    digit = "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"

    However, one thing I did notice that according to the MSN spec. there is
    supposed to be a "latest" ABNF file at the following URL:

    ftp://ftp.pwg.org/pub/pwg/standards/pwg5101-abnf.txt

    And that's not the correct URL for a lot of reasons......

    Ron and others,

    I'm surprised about the ABNF for the custom media size in the Media
    Standardized Names spec.

    I've noticed that I can specify any number of decimals for the x dimension,
    but only 1 decimal for the y dimension.

    Is that an oversight or is there some deeper thinking behind it, which I do
    not yet see?

    I'm dodging away a bit by switching from inch to the smaller mm, but of
    course I'm still not perfect.

    Regards

    Norbert
