Alfred's comment about updating the IANA registry for pkcs7-smime and pkcs7-signature got me to thinking about the smime-types that are currently used. signed-data, enveloped-data, certs-only, and compressed-data are addressed in RFC 3851 but the other content types we've defined (authenticated-data, encrypted-data, and authEnveloped-data) and others (content-with-attributes, content-collection, and others) don't have smime-types defined. Are these others used/defined someplace I don’t know about?
