You characterized the encoding of libraries as MIME messages
as an "alternative" to the <language> specification.  I don't
want to have to write my portable Scheme code as MIME messages,
however.  How is portable Scheme code supposed to specify the
report-revision=6 stuff without using the MIME encoding?
