+In all cases, if `route_id` is provided in addition to `trip_id`, then the `route_id` must be the same `route_id` as assigned to the given trip in GTFS trips.txt.
 
 The `trip_id` field cannot, by itself or in combination with other TripDescriptor fields, be used to identify multiple trip instances. For example, a TripDescriptor should never specify trip_id by itself for GTFS frequencies.txt exact_times=0 trips because start_time is also required to resolve to a single trip instance starting at a specific time of the day. If the TripDescriptor does not resolve to a single trip instance (i.e., it resolves to zero or multiple trip instances), it is considered an error and the entity containing the erroneous TripDescriptor may be discarded by consumers.
