Actually, yes, there is.  I really don't see how RFC 2049 could possibly
be any clearer.

I don't think there's much need to go farther afield into other MIME
documents when RFC 2049 is as clear as crystal and when we explicitly
stated in RFC 5536 that all user agents complying with RFC 5536 MUST meet
the definition of MIME conformance in RFC 2049.

(This does not, as pointed out elsewhere in the thread, imply that servers
have to reject messages generated by non-conformant user agents.)
