As the responsible AD for this conflict review I have concluded that this work is related to IETF work done in WG SPRING, but this relationship does not prevent publishing.

I have reviewed this document and also reviewed the SPRING mailing list for any discussion. The work presented here is experiemental and an alternative approach to work already concluded within the IETF. The SPRING WG concluded that they did not have consensus to adopt the work into their working group; during discussion the working group felt that the complexity of adding another altmark was not warranted by the claimed improvement over the IPv6 extension header altmark.  So the WG declined to undertake the effort.
