Yes, but a non-multipart/encrypted-aware MUA will not understand that it 
should look at the protocol parameter to process the data.  It will probably 
treat the multipart/encrypted as multipart/mixed, in which case the typing 
information in the second part (i.e. application/foo) would be *very* 
helpful...

There was probably some discussion surrounding this in the security multiparts 
camp when it was decided that the second part should be 
application/octet-stream.  Ned?
