RFC 1521 asks for IANA registration of values of the "charset"
parameter:

No registration procedure for character sets is specified in
RFC 1521, though.

The current Internet Draft draft-ietf-822ext-mime-reg-03.txt,
"Multipurpose Internet Mail Extensions (MIME) Part Four:
Registration Procedures", says:

: Registration of character sets for use in MIME is covered
: elsewhere and is no longer addressed by this document.

Which document cover the registration of character sets, then?

The IANA register file at
< ftp://ftp.isi.edu/in-notes/iana/assignments/character-sets >
states:

% These are the official names for character sets that may be used in
% the Internet and may be referred to in Internet documentation.

Many of the registered names have been taken from the
informational RFC 1345. Is it necessary to write an RFC to get a
new character set registered? Is it sufficient to do that?

I'm asking these questions, since I've noticed that part 10 of
ISO 8859 is not included in the IANA registry. That standard was
published in 1992:

   ISO/IEC 8859-10:1992(E)
   Information technology -- 8-bit single-byte coded graphic
      character sets -- Part 10: Latin alphabet No. 6
