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?
