The registration done by the S/MIME documents was done assuming that there would be a MIME (Multipurpose Internet Mail Extensions) wrapping layer around each of the different enveloping contents; thus, there was no need to include more than one item in each smime- type. This is no longer the case with some of the more advanced enveloping types. Some protocols such as the CMC (Certificate Management over Cryptographic Message Syntax) [RFC5273] have defined additional S/MIME types. New protocols that intend to wrap MIME content should continue to define a smime-type string; however, new protocols that intend to wrap non-MIME types should use this mechanism instead.
