COMMENT:
----------------------------------------------------------------------

- Please spell out DR at its first occurrence

- Not sure I understand what the intention of the following section is:
"6.4.  Host Built-in mB4 Function

   If the mB4 function is implemented in the host which is directly
   connected to an IPv6-only network, the host MUST implement the
   behaviors specified in Sections 6.1, 6.2, and 6.3.  The host MAY
   optimize the implementation to provide an Application Programming
   Interface (API) or kernel module to skip the IGMP-MLD Interworking
   Function.  Optimization considerations are out of scope of this
   specification."
  Why is this mentioned? Does that has to be normative?
