MIBenum value for ISO-10646-J-1?

[Bruce Lilly <blilly@erols.com>]

The current IANA character-sets registry has the following information
for ISO-10646-J-1:

Name: ISO-10646-J-1
Source: ISO 10646 Japanese, see RFC 1815.


No MIBenum, no aliases (cs* or otherwise), no indication of whether
or not the charset is suitable for MIME text/plain, and if so what the
preferred MIME name is), etc. (the sort of information provided for
other charsets in the registry).

Is that some sort of error in the IANA registry, and what information
should be be there?
