Hi Med,

This DISCUSS and the COMMENT from John came up again in the telechat earlier 
today.

This is clearly tripped up more than one person in their review process, so it 
is quite imaginable what it would do to an implementor. I do not have a good 
solution, and I am hoping this discussion comes up with a solution that is 
better than status quo.

The move to an IANA registry as the authoritative reference for the IEs is 
clearly the source of the problem. Is there something in the Updates to RFC 
5102 that indicates that the registry has moved to IANA? Or do folks have to 
read RFC 7012 to realize that? Would the registry pointing to RFC 5102, which 
would in turn point to RFC 7012 help?

But that may not be enough to satisfy the question that Paul is asking. Which 
RFC is being updated/obsoleted with the move to deprecate the 
ipv6ExtensionHeaders and tcpOptions IE. Does it make sense to update RFC 5102 
so folks know to reference this document, even if it is obsoleted by RFC 7102?
