Comment (2009-11-28 for -)
4.  Authentication

   Implementations conforming to this specification MUST support
   authentication for PIM-SM link-local messages.  Implementations
   conforming to this specification MUST support HMAC-SHA1.

A reference to the document that defines authentication using HMAC-SHA1
would be very helpful here.
And BTW, did you mean HMAC-SHA1-96 mentioned in RFC 4835?

5.  Confidentiality

   Implementations conforming to this specification SHOULD support
   confidentiality for PIM-SM.  Implementations supporting
   confidentiality MUST support AES-CBC with a 128-bit key.

As above.
