- Possible values:
- announcement: announcing a change of allowed speed
- execution: marking begin of section with changed allowed speed

*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.

Attributes:
- trainRelation: DEPRECATED, please use speedSection@refersToTrain instead;
Reference to the part of the train from where on the shown speed signal aspect is valid. Normally, a limiting speed signal aspect relates to the head of the train while a speed release refers to the end of the train. (optional; xs:string)
- Possible values:
- endOfTrain: The tail of the train should be located at the stopping place when the train has stopped.
- headOfTrain: The headof the train should be located at the stopping place when the train has stopped. This is the default setting.
- midOfTrain: The center of the train should be located at the stopping place when the train has stopped.,
- type: speed signal/panel type (announcement, execution) (optional;
xs:string)
- Possible values:
- announcement: announcing a change of allowed speed
- execution: marking begin of section with changed allowed speed

Semantics
The modelling of signalization is the same for a permanent and a temporary restriction. The fact stating that restriction is there only for some time is modelled as <speedSection>/@isTemporary="true".
Best Practice / Examples
The modelling of a signalized speed restriction and a <levelCrossingIS> with some problems is explained below. In the schematic plan below a temporary speed restriction is visualized.
Figure 1 - Signalized speed restriction (Example with German boards, a train going from the left to the right)
In Germany, for this, three signals are used (figure 1): announcement, indication and ending. The following signals are used for this for a train going from left to right:
1. <isSpeedSignal>/@type="announcement" of speed restriction (yellow one) (Germany: Shows the speed to be reached at A-board)
2. <isSpeedSignal>/@type="execution" of beginnig of speed restriction (red one) (German: Anfang)
3. <isSpeedSignal>/@type="execution " with higher mileage of an end of speed restriction (green one) (German: Ende)
