Comment (by cdaboo at apple.com):

 Section 12.1 defines how the 412 code should be used. Note that it says
 412 MUST NOT be returned when there are no conditional headers present.

 Section 16 talks about the precondition/postcondition behavior. Note that
 strictly speaking any valid 4xx status code could be used with those, its
 not just restricted to 403. But for all the CalDAV valid-xxx
 preconditions, 403 seems the most appropriate. In any case the rules for
 412 apply - 412 is only returned when evaluation of the condition request
 headers indicate an error.
