*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.
