Hi Lloyd,
You got me. Sorry, folks on the mailing list (including myself).
The problem that Angelo raised (or anyway he came to the mike and
told me about it) is what if the remote system admin tool wants
to place a new '
'static' locale in the device, but the device doesn't KNOW about
the locale. The alternative ASN.1 I posted lasted Thursday
evening (and Bob Pentecost commented on) removed the need
for the 'static' locale to already be KNOWN in the current
'prtLocalizationTable' (in some row reflecting ROM, etc).
Since the 'prtLocalizationTable' is 'read-only', the remote
system has to either:
a) populate a new row by out-of-band means OR
b) not depend on a pointer into that table, to specify
the (newly selected) 'static' locale.
See the note below and previous notes.
Cheers,

PS - I am deeply chagrined to have been guilty of not putting
the whole topic on the mailing list, since I regularly grumble
about just that. I just plain forgot. And I was anxious to
forward some ASN.1 to repair the 'problem', and forgot to
STATE it.

Ira,
For the benefit of people on the mailing list that were not a part
of the discussion at Nasha, would you please append the problem
that you are trying to solve with your latest modification?
Thanks,

Subject: PMP> Improved Static Localization (per Angelo C)
Reply To: PMP> New Printer MIB draft
Hi Lloyd, Angelo, and PMP folks, Thursday (26 June 1997)
During a break in this afternoon's IPP Telecon, Lloyd Young brought
hardcopy of yesterday's draft of the Printer MIB into the Nashua
conference room. A brief, lively discussion ensued.
Angelo Caruso suggested to me (and others in the conference room) that
an even BETTER way to specify the 'static' locale of a managed system
(than using an index into an entry in the 'prtLocalizationTable') was to
permit a remote management station (eg, system admin client tool) to Set
a locale which may NOT be currently 'known' to the managed system (ie,
the static locale may be 'opaque' to the managed system - not among the
locales 'known' via ROM/disk/etc).
ASN.1 for Angelo's suggestion follows (if someone else in the conference
room actually suggested the idea, my apologies - it was a little tricky
listening in this afternoon).
Cheers,
- Ira McDonald (outside consultant at Xerox)

DESCRIPTION
"The type for human-readable (NOT binary) string objects:
a) whose static locale (language, country, code set) shall be
composed of the English language (invariant), any country

Usage: If the locale country is NOT 'English-speaking', then
the code set shall nonetheless be NVT ASCII (a 7-bit code set!)
and keywords/tags shall be in the English language (specified
by an appropriate IETF or ISO standard, IANA registry, etc), but
other data need NOT be in 'English' (eg, French w/out accents)."
