Some feedback from a quick read of the charter text.

I have not clue what this means:

   [...] For these benchmark cases, the
   payload will be based on interface profile specific XML documents
   compressed with EXI.

Which benchmark cases is this text referring to? And why suddenly fix
a certain encoding?

I also do not understand the relationship of 4a) to 4). Since 4) talks
specifically about HTTP REST, how can 4a talk about non HTTP REST
protocols? I think 4) should say:

4) Specification how other protocols interface via a CoGII to CoAP.
   Separate specifications are envisioned zero or more of: SNMP, SMTP,
   SIP, and XMPP. [[Note: In the BOF it would be nice to figure out
   which of these are in the charter.]]

I find the text on various commissioning methods rather strange for
the charter of a working group. A working group charter item can be
the production of a BCP on commissioning methods. The current text
more looks like the initial draft of such a BCP, which does not belong
into a charter.

   CoAP will use CMS for object security. [...lost of more detail...]

This again looks like prescribing the solution - are we sure we do
understand that CMS is the right choice? Are we sure we understand how
CMS object security maps to other protocols mentioned under 4) and
that CoAP is supposed to interface to? Do we understand the overhead
of CMS security for say a simple meter reading? It might be better to
have a charter item to work on the security aspects and it might be
good to have security area advisors involved in this from the very
beginning.
