FeedEntity
FeedEntity
All entities should only be removed from a GTFS Realtime feed when they are no longer relevant to users. Feeds are considered to be stateless, meaning that each feed reflects the entire real-time state of the transit system. If an entity is provided in one feed instance but dropped in a subsequent feed update, it should be assumed that there is no real-time information for that entity.
