It would be nice to have some concrete examples in the draft, I find those 
easier to follow than descriptions. So, maybe something like:

DKIM-Signature: v=1; a=rsa-sha1; c=relaxed/relaxed; s=s1024; 
d=sender.example.com;
   
h=From:To:Reply-To:Date:Subject:MIME-Version:Content-Type:List-Unsubscribe:Message-ID;
 
   bh=...
   b=<this is a "strong" signature that covers the entire message>
DKIM-Signature: v=1; a=rsa-sha1; c=relaxed/relaxed; s=s1024; 
d=sender.example.com;
   h=From:To:Reply-To:Date; 
   l=<part of the message>
   bh=...
   b=<this is a "weak" signature that covers part of the message>
DKIM-Signature: v=1; a=rsa-sha1; c=relaxed/relaxed; s=s1024; 
d=discussionlists.org;
   
h=From:To:Reply-To:Date:Subject:MIME-Version:Content-Type:List-Unsubscribe:Message-ID;
 
   bh=...
   b=<this is the resigned message that hits that discussion lists before being 
redistributed>

Subject: [dmarc-ietf] So if you don't want a DKIM version bump ...

Here's the exact same proposal, except done with a new header
CDKIM-Signature rather than a DKIM version bump.

A new version of I-D, draft-levine-cdkim-00.txt
has been successfully submitted by John Levine and posted to the
IETF repository.

Abstract:
   The DKIM protocol applies a cryptographic signature to an e-mail
   message.  This specification defines a DKIM-like signature that
   includes the specification of external conditions that must be
   satisfied for a signature to be valid.
