Ira & Angelo,

Thanks for clearing up some of this for me. With your clarifications,
I've taken another look at the proposal and have some questions about
it (it seems that anytime someone looks closely at an area of the Printer
MIB, questions arise :-).

I'll start with Angelo's recent response and then go back to the original
proposal.

We need a list of the objects that are going to have their SYNTAX
changed to PrtEnglishASCIIString.

And now, the original proposal.

Is this object mandatory or optional?

I can't figure out if it is legal to update this object more than once ('may' and 'at most' are confusing). It seems to imply that it can be updated only once in the life of the printer.

It would also be good to specify that changing the value of this object will require the values of all the writable objects that are localized according to this one to be changed (or would they return to a default value?)

The above are all read-only objects, so this looks okay to me.

If a management application writes a value to prtConsoleDisplayBufferText, it must be localized according to prtGeneralConsoleLocalization. If the value of prtGeneralConsoleLocalization is changed, the management application should rewrite the value according to the new localization. (Note: We must be willing to live with this since this isn't a new problem.)

The above object is now prtGeneralPrinterName.

By adding the fourth textual convention PrtEnglishASCIILocaleString, I assume some of the objects under the 'PrtStaticLocaleDisplayString' list above would be moved. prtLocalizationLanguage and prtInputMediaName have been mentioned explicitly, while prtLocalizationCountry has been implied. It's not immediately clear to me which objects should have their SYNTAX changed to PrtEnglishASCIILocaleString (prtInputSerialNumber and prtOutputSerialNumber seem to be candidates).

SUMMARY
The chronology of this proposal has been:
4/20 - Proposal posted by Ira.
4/22 - PMP phone conference; Randy was to review proposal and send recommendation.
6/6 - Lloyd re-posts the proposal asking for discussion (which, in PWG fashion, ensues).
6/10 - Ira adds a fourth textual convention to his original proposal.

I appreciate the problem that Ira is trying to fix. However, at this point in time the proposal is incomplete since the list of objects that would be changed for syntax type PrtEnglishASCIILocaleString is not available. This proposal causes many changes in the document which makes for many opportunities to break things unintentionally. We are trying to get the Printer MIB published and have already missed our deadlines. Let's quit trying to fix "one more thing" and get the document out.
