* Tags
  * date tag
  Driver Licence people need CBOR tag for date from RFC3339 (1+2 tag). Joerg earlier proposed a tag for both time of day and date, with proposal to spend 1+1 tag.
  2 options: 
      1. register what Mike proposes and do Joerg proposal separately
      2. merge the proposals that would have both text and num date
   we can do registration as soon as the draft is stable.
   Carsten's preference to merge the proposal and register the date tag first, possibly later adding Joerg's other proposals
   Do we want to put the time of day tag and timezone in the same doc or separate?
   
   LL: difference between time and Mike's proposal?
   CB: full date, not point in time.

Ira: How do these types relate to the XML?
* https://www.w3.org/TR/2012/REC-xmlschema11-2-20120405/datatypes.html#dateTime
* https://www.w3.org/TR/2012/REC-xmlschema11-2-20120405/datatypes.html#time
* https://www.w3.org/TR/2012/REC-xmlschema11-2-20120405/datatypes.html#date
CB: we should look

LL: we should have cddl in the draft.

AP: add agenda slot

* Agenda IETF107
  - CBOR bis issues
  - date tag
  - CDDL freezer (if time allows)

MCR: CBOR bis would be an interesting topic for IAB tech plenary
CB: Maybe we should combine this with state of the work security (COSE, EAT )
JS: Need to write up something for the newsletter for COSE. Would make sense.
AP Francesca to send an email to Stephen.
