--------------------------------------
Type: Technical
Reported by: Marco Tiloca <marco.til...@ri.se>

Section: 4.4.1.1

Original Text
-------------
Payload (in CBOR diagnostic notation):
{
  / creds /            13: [h'a2026008a101a5010202410320012158

Corrected Text
--------------
Payload (in CBOR diagnostic notation):
{
  / num /               9: 12,
  / creds /            13: [h'a2026008a101a5010202410320012158

Notes
-----
The reported Figure 17 shows an example of 2.05 (Content) response to a FETCH 
request sent to the resource /ace-group/GROUPNAME/creds at the KDC.

In that example, the parameter 'num' is missing in the response, while the 
parameter has to be included according to the format of that response as 
defined in Section 4.4.1, i.e.:

> If all verifications succeed, the handler returns a 2.05 (Content) message 
> response with the payload formatted as a CBOR map, containing only the 
> following parameters from Section 4.3.1.
> 
> * 'num': encoding the version number of the current group keying material.
> * 'creds': encoding the list of authentication credentials of the selected 
> group members.
> * 'peer_roles': encoding the role(s) that each of the selected group members 
> has in the group. This parameter SHOULD be present, and it MAY be omitted 
> according to the same criteria defined for the Join Response (see Section 
> 4.3.1).
> * 'peer_identifiers': encoding the node identifier that each of the selected 
> group members has in the group.
