  Reference to a SCHEDULED STOP POINT.
  
  Reference to a STOP POINT.
- VisitNumber 0..1 VisitNumberType
  
  Sequence of visit to SCHEDULED STOP POINT.within VEHICLE JOURNEY. Increases monotonically, but not necessarily sequentially.
- Order 0..1 xsd:positiveInteger
  
  For implementations for which the overall Order is not used for VisitNumber, (i.e. if VisitNumberIsOrder is false) then can be used to associate the stop Order as well if useful.
- StopPointName 0..unbounded NaturalLanguageStringStructure
  
  Name of SCHEDULED STOP POINT. (Unbounded since SIRI 2.0)
choice 0..1
- ExtraCall 0..1 xsd:booleandefault false
  
  This CALL is an addition to the respective journey in the production timetable or to the previously sent prediction. If omitted: CALL is planned.
- Cancellation 0..1 CallCancellationdefault false
groupCallRealTimeInfoGroup 1..1

Information relating to real-time properties of call.
- PredictionInaccurate 0..1 xsd:booleandefault false
  
  Whether the prediction for a specific stop or the whole journey is considered to be of a useful accuracy or not. Default is 'false', i.e. prediction is considered to be accurate. If prediction is degraded, e.g. because of a situation, PredictionInaccurate is used to indicate a lowered quality of data. Inherited property. PredictionInaccurate can be used in combination with InCongestion, but is more general.
- PredictionInaccurateReason 0..1 PredictionInaccurateReasonEnumeration
  
  Can be used to inform the passenger about the reason for a change of the prediction (in)accuracy in case PredictionInaccurate is set to 'true'. (since SIRI 2.1)
- Occupancy 0..1 OccupancyEnumeration
  
  An approximate figure of how occupied the journey is after departing from a given stop, e.g. 'manySeatsAvailable' or 'standingRoomOnly'. If omitted: Passenger load is unknown. Occupancies and capacities for individual VEHICLEs, e.g. parts of a COMPOUND TRAIN, can also be specified in more detail for the departure on CALL level.
groupCallPropertyGroup 1..1

Elements describing the CALL Properties Values for these elements can be specified on an production VEHICLE JOURNEY CALL. Each real-time journey CALL takes its values from the corresponding dated VEHICLE JOURNEY CALL. The absence of a value on an real-time CALL l indicates that the value should be inherited (i) from any recent preceding update message for the same entity, or if there is no previous override, (ii) from its immediate parent entity.
- TimingPoint 0..1 xsd:booleandefault true
  
  Whether the stop is a TIMING POINT. Times for stops that are not timing points are sometimes interpolated crudely from the timing points, and may represent a lower level of accuracy. Default is 'true'.
- BoardingStretch 0..1 xsd:booleandefault false
  
  Whether this is a Hail and Ride Stop. Default is 'false'.
- RequestStop 0..1 xsd:booleandefault false
  
  Whether Vehicle stops only if requested explicitly by passenger. Default is 'false'.

groupOnwardsCallGroup 1..1

Elements describing the CALL. Values for these elements can be specified on an production VEHICLE JOURNEY CALL. Each real-time journey CALL takes its values from the corresponding dated VEHICLE JOURNEY CALL. The absence of a value on an real-time CALL l indicates that the value should be inherited (i) from any recent preceding update message for the same entity, or if there is no previous override, (ii) from its immediate parent entity.

    - ArrivalPredictionUnknown 1..1 EmptyType
      
      If the producer is (temporarily) not able to deliver real-time predictions (e.g. because of a connection loss), he has various options (and combinations of them) to inform the consumer: (i) set Monitored to 'false' (ii) transmit ExpectedArrivalTime together with "PredictionInaccurate=true" (iii) drop/omit ExpectedArrivalTime (iv) set ArrivalStatus to 'noReport' However, this might introduce ambiguity: e.g. option (iii) might be interpreted as "on time" by one consumer, but also as "indefinite delay" by another consumer. To avoid this, the producer should transmit xxxPredictionUnknown instead of any expected times. (since SIRI 2.1)
- groupMonitoredStopArrivalStatusGroup 1..1
  
  Elements describing the arrival status of a VEHICLE at a stop.
  - ArrivalStatus 0..1 CallStatusEnumeration

    Bay or platform (QUAY) name to show passenger i.e. expected platform for vehicle to arrive at. Inheritable property. Can be omitted if the same as the DeparturePlatformName If there no arrival platform name separate from the departure platform name, the precedence is: (i) any arrival platform on any related dated timetable element, (ii) any departure platform name on this estimated element; (iii) any departure platform name on any related dated timetable CALL.

(since SIRI 2.1) Examples: - "towards A" or "towards sector A" if the QUAY is separated into sub-QUAYs or so called sectors. This would be equivalent to the vehicle arriving at sector A first when approaching the QUAY with sectors A-B-C-D. If the arriving vehicle is represented as an arrow, "towards A" would be abstracted as "=> A-B-C-D". - "towards 0" or "towards reference point 0" if sectors are not available or the QUAY has a reference point, e.g. for measuring the length of the QUAY, identified by "0". This would be equivalent to the vehicle arriving at this reference point first when approaching the QUAY. If the arriving vehicle is represented as an arrow, "towards 0" would be abstracted as "=> 0...100". "100" (as in percent) could denote the opposite side of the QUAY (measured at the full length of the QUAY with respect to the reference point). It is advised to specify a reference point that is meaningful for passengers on location.
  - ArrivalOperatorRefs 0..unbounded OperatorRefStructure
    
    OPERATORs of of service up until arrival. May change for departure. (since SIRI 2.0).

    - EarliestExpectedDepartureTime 0..1 xsd:dateTime
      
      Earliest time at which VEHICLE may leave the stop. Used to secure connections. Used for passenger announcements.

If absent assume to be the same as Earliest expected departure time. (since SIRI 2.0)
  - ExpectedLatestPassengerAccessTime 0..1 xsd:dateTime
    
    Latest expected time at which a PASSENGER should aim to arrive at the STOP PLACE containing the stop. This time may be earlier than the VEHICLE departure times and may include time for processes such as checkin, security, etc.(As specified by CHECK CONSTRAINT DELAYs in the underlying data). If absent assume to be the same as Earliest expected departure time. (since SIRI 2.0)
- groupMonitoredStopDepartureStatusGroup 1..1
  
  Elements describing the departure status of a VEHICLE from a stop.
  - DepartureStatus 0..1 CallStatusEnumeration
    
    Classification of the timeliness of the departure part of the CALL, according to a fixed list of values.

(since SIRI 2.1) Examples: - "towards A" or "towards sector A" if the QUAY is separated into sub-QUAYs or so called sectors. This would be equivalent to the vehicle departing in the direction of sector A on a QUAY with sectors A-B-C-D. If the departing vehicle is represented as an arrow, "towards A" would be abstracted as "<= A-B-C-D". - "towards 0" or "towards reference point 0" if sectors are not available or the QUAY has a reference point, e.g. for measuring the length of the QUAY, identified by "0". This would be equivalent to the vehicle departing in the direction of this reference point. If the departing vehicle is represented as an arrow, "towards 0" would be abstracted as "<= 0...100". "100" (as in percent) could denote the opposite side of the QUAY (measured at the full length of the QUAY with respect to the reference point).
