VehiclePosition.current_status default value

[ismailadioufy-beep]

Hello all,
I currently have a doubt regarding VehiclePosition.current_status default value

When HasCurrentStatus = false, current_status default value is supposed to be 0 (INCOMING_AT = 0; as a first enum value) or 4 as mentioned below (Protobuf - General Transit Feed Specification)

enum VehicleStopStatus {
// The vehicle is just about to arrive at the stop (on a stop
// display, the vehicle symbol typically flashes).
INCOMING_AT = 0;

// The vehicle is standing at the stop.
STOPPED_AT = 1;

// The vehicle has departed and is in transit to the next stop.
IN_TRANSIT_TO = 2;

}
// The exact status of the vehicle with respect to the current stop.
// Ignored if current_stop_sequence is missing.
optional VehicleStopStatus current_status = 4 [default = IN_TRANSIT_TO];

Thank for your support

@ismailadioufy-beep the default value is "IN_TRANSIT_TO". 0 and 4 are field numbers used in protobuf, just an id for the field.
