Thanks Kepeng for the comments.

Please consider that our draft was based upon coap-04 and
observe-01... Now needs some updates as you noted.

We were planning to do so, but we waited for some comments before
expanding that section and go over with more text.

We plan to to do this in the next revision, as said before.

Sure that is TBD and we will be probably merging with Klaus on this section.

Yes, as said.

Best,
