It depends on how extensive the changes are that you are suggesting. 
The word "re-write" implies that we should through out the current 
section and start over, to which I disagree.  I'm willing to 
lower-case some of the terms though and modify individual sentences 
and paragraphs.

I agree with 5.1, para 2, but I disagree with 5.3 --- the point of 
that is that something somehow SHOULD convert the message to 7-bit 
MIME before presentation to the DKIM algorithm in order to maximize 
interoperability.  The converting agent might be an MUA, it might be 
an MSA, it might even be the MTA, but in any case that conversion 
SHOULD be done.
