Hi Rick,

Given that the underlying source data are a in table of language/charset tuples,
the parallel lists is the only reasonable choice, I think.

The sparse lists are meaningless - if you don't know that ISO-8859-1 won't
work with Thai, you could make a lousy assumption.  Of course, if we allowed
(eventually) a DMTF CIM method to change current charset *without* changing
current language, then that method would be impossible to implement in the
real world.

How about if we DEPRECATE all four properties (current and supported) and
add explicit natural language tags on the XxxDescription localized description
properties in the daughter subunit classes?  (Note that ALL CIM strings are
Unicode, so the charset's meaningless anyway for the CIM interface).

Comments?

Cheers,
- Ira
