Thanks for the review.  Frank has already commented on this, but I'll
add one more note.  I have also posted a reply to the DNS Stuff forum.

An SPF-compliant check SHOULD try to look up and use a record of the SPF type 
first, before falling back to the TXT type.  However, the client MAY also 
look up both types in parallel.
If, for a domain, both types are obtained but their contents do not match, 
the SPF client SHOULD return a "PermError" result.

The "PermError" rule is NOT mentioned in 4.5 Selecting records.
What to do if both rules are not identical but they both exclude or allow the 
domain in question?
Still the SPF client SHOULD return a "PermError" result?

I have moved all of the text about the different lookups out of
section 3.1.1.  I have updated section 4.4 "Record Lookup" to mention
that the lookups can be performed in parallel and I have updated
seciton 4.5 "Selecting Records" to define the PermError results
