Section 5., paragraph 1: > This section summarizes the requirements; if there is a difference in > this summary and the text in the main body of the document, the main > body takes precedence. Either make sure that there are no differences, or remove this section (the document isn't long enough to need a summary.)

This document uses acronyms, such as SDP, without expansion or reference. Please fix. Nit: to IP multicast group addresses. This profile of functionality is the expected best practice for residential access routers small Missing "," between "access routers" and "small".

Nit caught by Gonzalo Camarillo during Gen-ART Review: The word 'section' is typically capitalized in sentences like '... in Section 3.2 of [RFC4605]'.

REQ-6 states:
A NAT MUST NOT forward administratively scoped IP multicast
traffic (239.0.0.0/8) [RFC2365] from its 'inside'
interface(s) to its 'outside' interface, unless the NAT has
been configured to do so.
The semantics of "MUST NOT ... unless configured to do so" are tricky.
As far as I can tell, this requirement is only imposed on the default
configuration. If that is correct, it might be clearer to state the requirement
in terms of the default configuration:
The NAT's default configuration MUST NOT forward
administratively scoped IP multicast
traffic (239.0.0.0/8) [RFC2365] from its 'inside'
interface(s) to its 'outside' interface.
