John also provided some text for that section and Keyur suggested that we log and treat as a WITHDRAW. This would read as: "This document specifies that a BGP speaker MUST NOT originate or propagate a route with an AS number of zero. If a BGP speaker receives a route which has an AS number of zero in the AS_PATH attribute, it SHOULD be logged and treated as a WITHDRAW." This avoids having a normative reverence to the optional-transitive draft and is (IMO) a little clearer. It also saves optional-transitive from referencing this, and so we avoid the deadlock...
