That surprises me, since for permanent registrations the registration procedure is specification required, and so a specification going into detail for that field should be provided. Maybe what this document meant to say was that draft-ietf-httpbis-targeted-cache-control should be *one of* the specifications for new registrations?

This specification contains all of the necessary details to parse, serialise, understand and apply the semantics of those headers -- the only thing it lacks is the target for the semantics. In most cases, that will be obvious based upon the context -- e.g., Akamai-Cache-Control with a reference to this document is pretty clear about its semantics, and in a pinch Akamai can add some information in its local documentation (perhaps meriting an additional link or note in the registry).
