If the message contains a C-T-E header in the 822 headers, it applies
to the _entire_ message body (i.e. everything after the CRLFCRLF 822
header/body separator).

If any of the mime body parts contain a C-T-E header the 822 headers
should *not* contain a C-T-E header. Instead, each mime body part
should have an explicit C-T-E header (or an implicit "C-T-E: 7bit"
indicated by the absence of a C-T-E header on a particular body part).

As for the "nyah nyah" blob at the beginning of a mime multipart,
consider that that text will only be displayed by non-mime-aware
software, therefore it only makes sense to include only US-ASCII
characters in that text. You could also argue that in a multipart
message the "nyah nyah" part isn't really a mime body part (since
you can't reference it via mime), and therefore falls outside the
mime domain. If it's not mime, it is by definition 7bit content.

If you really want a definitive "ruling" on this you should talk
to Ned Freed.
