> The IESG has approved the following document:
> - 'Brainpool Elliptic Curves for the IKE Group Description Registry'
>  (draft-harkins-brainpool-ike-groups-04.txt) as Informational RFC
> This document has been reviewed in the IETF but is not the product of an
> IETF Working Group.
> The IESG contact person is Sean Turner.
> A URL of this Internet Draft is:
> http://datatracker.ietf.org/doc/draft-harkins-brainpool-ike-groups/
> Technical Summary
> The draft allocates code points for four new elliptic curve domain
> parameter sets (ECC Brainpool curves from RFC 5639)
> over finite prime fields into a registry that was established by the IKEv1
> (https://www.iana.org/assignments/ipsec-registry) but is used by other
> protocols (IEEE 802.11aa, IEEE 802.11s, RFC 5931). 
> Working Group Summary
> The draft was discussed quite controversially on the WG mailing list.
> There are persons in the WG that strongly feel
> that no further code points should be defined for IKEv1 because the
> protocol has been deprecated long ago (by RFC 4306).
> Other persons in the WG argued that IKEv1 is still widely used in
> practice and, furthermore, other code points have been
> assigned previously to the same name space after IKEv1 was obsoleted. No
> consensus could be achieved on this topic. On
> the other hand, the ADs received an informal liaison statement from IEEE
> 802.11
> (https://datatracker.ietf.org/liaison/1181/) requesting code point
> assignments for these curves in the IKEv1 registry.
> IEEE standards 802.11aa and 802.11s are using this name space of the
> IKEv1 registry, and these specs are apparently not
> up for change until 2015. The matter was discussed at the SAAG meeting
> among the ADs and the WG members present and it
> was decided to publish an internet-draft that requests these code points
> but also requires IANA to add a note that they
> are not for IKEv1. In the WG discussion following its publication,
> concerns were uttered that the note won't be enough
> to stop people asking for IKEv1 products to support these new code
> points and to prevent implementers to use them for
> IKEv1. On the other hand, it was expressed that requiring the IEEE specs
> to point to another (new) registry is probably
> not possible due to their publishing cycle. Alternative solutions were
> discussed, e.g. to include in the registry only a
> link pointing to another registry where the actual values are listed.
> Eventually, the approach of the draft, i.e. to
> include a note "not for IKE" in the registry, was widely considered the
> best way forward.
> After some comments on earlier versions, an announcement of a revised
> draft on the ipsecme mailing list did not result
> in any further comments.
> There was agreement that the draft shall not be a WG document. 
> Document Quality
> Some specific comments of Tim Polk were accommodated in a revision.
