It seems that 'logic' got in my way. RFC 2046 says this about
"Content-Type: multipart/mixed":

"This Content-Type value indicates that the content consists of one
or more parts"

So, a single part is permissible here. Anyway, the problem should be
cleared up when the text/calendar problem is cleared up.
