[ietf-dkim] SSP issues

[Jim Fenton <[e-mail]>]

What we had hoped to do in the next revision of the allman-ssp draft was to unify it as much as possible with Phill Hallam-Baker's draft.  I opened three new issues on April 16 that I think need to be resolved in order to do that.

(1) Use of XPTR records for SSP.  The idea here is to create a more general policy mechanism that can be used by WS-* and such.  There were about 20 messages discussing this from 5 people.  I'm not reading a clear consensus on this.

(2) SSP record type (TXT vs. something new). Only 4 messages in discussion, mostly saying "if you support TXT, don't bother with anything else."  Again, no clear consensus.

(3) Upward query vs. wildcard publication.  27 messages in discussion from 15 people.  Most of the discussion was a rehash of the idea of associating semantics with DNS zone-cuts, which we had already discussed and rejected.  I have also been trying to get an opinion from DNSOP on the idea of a one-level upward search (which I think solves 90% of the problem), but haven't gotten any response.

So I don't know what to write in a revision of the draft.  I could just write my opinions, but that's basically what's in the draft-allman-dkim-ssp-02 draft already and doesn't make any progress toward unifying the different proposals.  I want to get something done soon, well before the July 2 deadline.
