Ryan,

If 11.3 doesn't apply to 11.1.1 _at all_, then a CA could rely on a 
Domain Authorization Document _forever_, as long as it was "(ii) used by 
the CA to verify a previously issued certificate and that the Domain 
Name's WHOIS record has not been modified since the previous 
certificate's issuance."

Surely the intent was that 11.3 should cap the length of time that a CA 
may rely on a Domain Authorization Document to a maximum of 39 months?

I think the intent of 11.3 was to impose a restriction rather than to 
grant permission.  Therefore, it would've made a lot more sense for it 
to say "The CA MUST NOT <list of restrictions>" rather than "The CA MAY...".
