Re: [ietf-dkim] errata revision: opaque

Looks good to me.

I have a mild reservation in that "opaque" struck me as the most
appropriate term to begin with, but I'll certainly be OK with this.

Folks,

The following is offered to prime the discussion/decision process for the one 
of
the pending Errata items, developed in the SF working group meeting. It 
reflects
what I heard as the gist of the group preference. Obviously, I might have
entirely misunderstood...

So, anything that permits progress is encouraged, such as "looks good", 
"change
x to y", and "replace the whole thing with this different chunk of text". 
 There
are no doubt other constructive responses, but this ought to establish the 
tone...


"Old" refers to the Errata I-D; "New" is the proffered replacement.


6.  RFC4871 Section 2.9 Signing Domain Identifier (SDID)

    Old:
      A single, opaque value that is the mandatory payload output of
      DKIM and which refers to the identity claiming responsibility for
      the introduction of a message into the mail stream.  It is

    New:
      A single domain name that is the mandatory payload output of
      DKIM and that refers to the identity claiming responsibility for
      introduction of a message into the mail stream.  For DKIM
      processing, the name has only basic domain name semantics; any
      possible owner-specific semantics is outside the scope of DKIM.


7.  RFC4871 Section 2.10 Agent or User Identifier (AUID)

    Old:
      A single, opaque value that identifies the agent or user on behalf
      of whom the SDID has taken responsibility.

    New:
      A single domain name that identifies the agent or user on behalf
      of whom the SDID has taken responsibility.  For DKIM
      processing, the name has only basic domain name semantics; any
      possible owner-specific semantics is outside the scope of DKIM.


12.  RFC4871 Section 3.9 Relationship Between SDID and AUID

    Old:
      Hence, DKIM delivers to receive-side Identity Assessors
      responsible Identifiers that are opaque to the assessor.  Their
      sub-structures and particular semantics are not publicly defined
      and, therefore, cannot be assumed by an Identity Assessor.

    New:
      Hence, DKIM's mandatory delivery to a receive-side Identity Assessor
      is a single domain name.  Within the scope of its use as DKIM output,
      the name has only basic domain name semantics; any possible
      owner-specific semantics is outside the scope of DKIM. That is,
      within its role as a DKIM identifier, additional semantics cannot
      be assumed by an Identity Assessor.


OK.  Start shooting.
