I didn’t include a direct reference in the Section as incorporates the changes, but it is included in Appendix B describing the changes.

No current intent to deprecate RFC5952 as it updates RFC4291.  I don’t see very much value in deprecating (Historic?) the updating RFCs.

That makes sense.  Something like a new paragraph at the end of the section like:

Additional defined multicast address can be found in the IANA IPv6 Multicast Address Allocation registry [XXX]

XXX: http://www.iana.org/assignments/ipv6-multicast-addresses/ipv6-multicast-addresses.xhtml.

It was capitalized in RFC4291.  It looks like the change was introduced in draft-hinden-6man-rfc4291bis-01.   I think may have been accidentally part of changing the text addresses to lower case as part of the RFC5952 update.  I agree it should be the way it was in RFC4291.  Will change.

Thanks,
Bob
