Hi,

I object strongly to the unchanged formulation of section 3.1.1 (Discovery).
It mandates DNS-SD when IMHO it should mandate either DNS-SD or a GRASP
based method, as we discussed in Berlin. As I've said a few times,
I don't really care whether the GRASP method is based on the Flood
mechanism or the Discovery/Synchronize mechanism, or a Discovery/Negotiate
mechanism as Michael R proposed. But we look collectively foolish
if we do not use a GRASP mechanism within the AN environment.

At least, I want to see a place holder for this in the -04 draft.
Basically it would look like

[the pledge]

b.  MUST:

 either b1. Performs DNS-based Service Discovery [RFC6763]...

 or b2. Performs GRASP-based Discovery [details TBD since we are out of time]

and appropriate text somwhere about what the proxy does (i.e. MUST support
both discovery methods).

In 3.2.1 (CoAP connection to Registrar) there is a passing reference
to GRASP, without a citation, and the same for the ACP, without a citation.
At the minimum those need to cite the relevant drafts. There's the same
choice for how the proxy discovers the registrar (Flood, Discovery/Synchronize
or Discovery/Negotiate). Also, the ACP isn't mandatory for GRASP - we
could use Synchronize or Negotiate securely via TLS, if we had to.

Regards
   Brian
