    I personally disagree with this decision, especially since there
    *are* consumer inkjets today (and for the past several years, in
    fact) that support roll (sometimes called "banner") media of
    more-or-less arbitrary length.

    I understand that some things about roll media may be out of scope
    (cutting, marking, etc.), but to ignore roll media entirely will
    make this specification useless.

    I merely propose that the following media type be added to the
    current specification:

        'roll' - A continuous roll of media whose limits are
                 described by the custom-min and custom-max sizes.

    Again, it is *extremely* important that we support roll media
    types because they are available for many consumer inkjets as
    well as high-end devices. Most of these devices *do* need to
    know that you want to use roll fed media, and if no keyword
    is defined for it then you'll end up with a different name for
    each implementation.

    I agree, however, that things like cutter control and marking
    the page area on the media are beyond the scope of this
    specification, so any mention of roll media should be limited
    to the media type and not any of the other issues.

    Should we also then define the front and back coating, as is done
    for the other standards? Or are we just going to define the
    names of the values and leave the attribute naming up to the
    protocol folks?

    Yes, this will work perfectly well.
