I'm not sure I understand why RATS is on the CC.

A URL is rather bulky for some uses, but if the CBOR is encoding thousands of
items in a compact form, then the amortization of the tag makes sense.

draft-ietf-cbor-file-magic provides a similiar mechanism with the
recommendation that one go for a 4-byte tag from the FCFS space.
yes, that involves a trip through IANA... an email and a delay of perhaps a
week.

I agree with Carsten that the document is a bit underspecified.
