Re: [core] I-D Action: draft-ietf-core-oscore-groupcomm-19.txt

[Marco Tiloca <[e-mail]>]

Hi all,

This version -19 addresses the only remaining point from the previous 
revision, i.e., presenting the handling of all multiple responses in a 
unified way, instead of separately for Observe notifications and 
non-notifications.

The authors believe that this version addresses all the comments from 
Christian's Shepherd review [1] (thanks a lot again!)

Best,
/Marco
