Attributes:
- indicatorType: The type of the additional signal indicator which appears on the HMI near the signal. (optional;
xs:string; patterns: other:w{2,}; consider Dev:UsingAny too.)
- Possible values:
- cautiousDriving: indicating route entry into occupied or dead end track requiring special caution
- directionIndicator: indicates the alphanumerical value for the direction as set from this main signal
- distantDirectionIndicator: shows the alphanumerical value for the direction to be expected on the next main signal
- distantJunctionIndicator: shows the route value to be expected on the next main (junction) signal as used for route signalling
- distantShortBrakingDistance: shows the indication to expect the next main signal will show the indication for a reduced braking distance from the next main signal (PLK: W19)
- distantSpeedIndicator: shows the speed value to be expected on next main signal
- junctionIndicator: indicates the route value as set from this main (junction) signal as used for route signalling
- shortBrakingDistance: indicates that the next main signal follows within reduced braking distance (PLK: W20)
- speedIndicator: indicates the speed value valid from the position of this main signal
- wrongTrackDriving: indicates the change to the track of opposite direction for driving (DV301: Zs7, PLK: W24),
- isNotWired: The indicator is physically present as a board, which has only one aspect. Thus it cannot be steered from the interlocking but has to be considered for correct aspect calculation by interlocking. (optional;
xs:boolean),
- elementNumber: number of the element in the set of interlocking data (optional;
xs:nonNegativeInteger),
- id: the identifier of the object; this can be either of type xs:ID or UUID (obligatory;
xs:ID); compare: Dev:Identities

*Notice:
Elements may have different parent elements. As a consequence they may be used in different contexts.
Please, consider this as well as a user of this wiki as when developing this documentation further.
Aspects that are only relevant with respect to one of several parents should be explained exclusively in the documentation of the respective parent element.

Semantics
Best Practice / Examples
The <signalIndicator> element is for rather special purpose. In some cases the signal is fitted with additional indicators on the mast which might be activated in combination of the normal signal aspect or even completely independent. However, the indicator status is to be indicated with a separate graphic element on the HMI independent of the signal status according to the rules of the infrastructure manager. A good example is the subsidary signal for cautious driving in Norway.
In order to access and control this additional element for the <signalBox> or the <controller> (HMI) this asset is defined.
- @elementNumber - A positive integer number unique within one <signalBox> to index the element in internal lists of engineering data.
- @id - The unique identifier used to reference this element within railML.
- @indicatorType - There is currently only cautiousDriving defined for use. Other values might be defined to extend the list.
- <hasCommand> - In case the indicator has commands (independent from the signal) the can be referred here. They need to be predefined for the <specificInfrastructureManager>.
- <hasIndication> - Any kind of defined status indication can be referred here.
