Does the IANA currently discriminate between _character set_ and _content
transfer encoding_ in a way similar as MIME does? IN my feeling, there is
only one underlying charter set (Unicode/ISO 10646), but there are several
content transfer encodings:

32bit or UCS-4
16bit or UCS-2 (including UTF-16)

It will be very helpful to have different tags for the character set itself
and the transformation format. Otherwise you end up in a product
(ISO-10646 version) * (transformation-format) of different character sets
to be registered -- clearly an uneconomical approach.
