I have done a quick update of the draft-bormann-cbor-cddl-map-like-data tags specification.

If needed, we can discuss this tomorrow.

The main issue remaining is whether the FAlist form [1] is all we need, or whether we maybe do need one or more of the other representation forms as well.

Grüße, Carsten
