    Hi Juergen,

    This is a tough question. For six years now every Xerox product has
    shipped with 'prtAlertIndex' at 'read-only' to preserve the content
    of the notification. I have seen this done at several other printer
    vendors. To date, there is no identified shipping implementation
    that leaves 'prtAlertIndex' at 'not-accessible' (that was only one
    of several compile errors in the RFC 1759 text - I've never seen a
    compiler that would accept RFC 1759 unmodified, but I suppose it's
    possible).

    Our WG concensus to change the published version to 'read-only' is
    in order to align with all known shipping implementations (who all
    did it by hand-edit themselves).

    Cheers,
    - Ira McDonald, consulting architect at Xerox

    There are existing fielded implementations that implement
    prtAlertIndex not-accessible. So what is the point in making it
    read-only just to kind of fix the notification? If it is true that
    people had problems to implement the notification because
    prtAlertIndex is not-accessible, then this would be a data point to
    actually fix the notification by providing a new one that does it
    right.

    Changing prtAlertIndex from not-accessible to read-only to fix the
    notification kind is IMHO heading in the wrong direction.
