RFC 6381 is referenced in the spec at 4.2.2, 4.3.2 and 4.4.2 - but not provided in the References section. This is: https://tools.ietf.org/html/rfc6381, The 'Codecs' and 'Profiles' Parameters for "Bucket" Media Types. Since proper formatting of the MIME type and sub-type are specified in RFC 6381, it should be a normative reference in the spec.
