See definition of `trips.shape_id` in (CSV) GTFS.
If a shape is neither defined in (CSV) GTFS nor in real-time, the shape is considered unknown. This field can refer to a shape defined in the (CSV) GTFS in shapes.txt or a `Shape` in the same (protobuf) real-time feed. The order of stops (stop sequences) for this trip must remain the same as (CSV) GTFS. If it refers to a `Shape` entity in the same real-time feed, the value of this field should be the one of the `shape_id` inside the entity, and _not_ the `id` of `FeedEntity`.
Stops that are a part of the original trip but will no longer be made, such as when a detour occurs, should be marked as schedule_relationship=SKIPPED or more details can be provided via a `TripModifications` message.
