Ah thanks, I like that much better.

I suggest:

   INFORMATIVE IMPLEMENTATION NOTE:

   The DKIM specification advises that if a message fails 
verification, it should be
   treated as an unsigned message.  A verifier may elect to report 
"neutral" instead of
   "fail" to discourage needlessly harsh reactions from downstream 
agents such as message
   rejection based on a "fail" result.
