Re: [ietf-dkim] [Technical Errata Reported] RFC6376 (3758)

This one's right, of course: no one uses "v=DKIM1"; it's always "v=1".
 Authors, was this just left in from the "transition from DK" days?

The following errata report has been submitted for RFC6376,
"DomainKeys Identified Mail (DKIM) Signatures".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata_search.php?rfc=6376&eid=3758

--------------------------------------
Type: Technical
Reported by: Majid Tajamolian & Nazilla Karkon <mjdtjm(_at_)gmail(_dot_)com>

Section: 3.6.1.

Original Text
-------------
v= Version of the DKIM key record (plain-text; RECOMMENDED, default
      is "DKIM1").  If specified, this tag MUST be set to "DKIM1"
      (without the quotes).  This tag MUST be the first tag in the
      record.  Records beginning with a "v=" tag with any other value
      MUST be discarded.  Note that Verifiers must do a string
      comparison on this value; for example, "DKIM1" is not the same as
      "DKIM1.0".

Corrected Text
--------------
v= Version of the DKIM key record (plain-text; RECOMMENDED, default
      is "1").  If specified, this tag MUST be set to "1"
      (without the quotes).  This tag MUST be the first tag in the
      record.  Records beginning with a "v=" tag with any other value
      MUST be discarded.  Note that Verifiers must do a string
      comparison on this value; for example, "1" is not the same as
      "1.0".

Notes
-----
The "DKIM" prefix in the version field is unnecessary.
for example the followings are snipped from an actual email via gmail.com:

DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed;
        d=gmail.com; s=20120113;
        h=mime-version:from:date:message-id:subject:to:content-type;
