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.
