Good call. Would it make both parts clearer if the introduction instead said: Because the information returned in this protocol only applies to recursive resolvers, servers that are acting as both authoritative servers and recursive resolvers MUST only answer queries that are intended for the recursive resolver portion of the server. Servers that are only authoritative servers MUST NOT answer queries that are defined in this protocol. --Paul Hoffman
