PS: Just so's I can reconstruct it for myself later, the construct
might end up something like:
   body-hash = Hash1(nonce, body)
   sig-bits  = Private-key(Hash2(nonce,header-stuff, body-hash))

Actually the "data" hash would be more like:

  data-hash = Hash1(nonce, header-stuff, body)
  sig-bits  = Private-key(Hash2(nonce, DKIM-Signature-field))

I.e. The digital signature is only on the DKIM-Signature field,
nothing else.
