Olle: In general, I like the proposal, *except* that it would allow a
charset to be associated with any MIME parameter. For some parameters,
a charset might be meaningless (when the parameter describes non-
character data); for others, there is a sometimes a need to limit the
charsets which might be used.
Any proposal to extend parameters to handle different character sets,
needs to fully specify what happens when the character set in the
parameter isn't understood by the recipient's mail reader.
For example, it's completely unreasonable to expect a mail reader
to recognize a file name in any MIME character set and translate
that character set to whatever is used locally.
