Attributes:
- distance: Distance in metres from exit signal to danger point. Optional because one may also derive this distance from the track asset where the danger point is situated. (optional;
xs:decimal),
- releaseSpeed: Release speed in km/h associated with the danger point. (optional;
xs:decimal),
- releaseSpeedSource: Allows specifying that the release speed may be taken from either an onboard calculation or the national values. (optional;
xs:string)
- Possible values:
- calculatedOnBoard: Indicates that the release speed for the danger point is calculated on board. Corresponds to the ETCS special value for M_RELEASEDP of 126
- nationalValues: Indicates that the release speed for the danger point is taken from national values. Corresponds to the ETCS special value for M_RELEASEDP of 127,
- elementNumber: element number of the object for internal referencing in the engineering 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
A route exit may refer to a danger point. The danger point defines the position in advance of the destination signal up to where a train is likely to be safe. The danger point is not necessarily related to a train detection element.
The element can take the following information:
- @distance – This is the distance in metres from the destination signal to the physical danger point.
- @releaseSpeed – The release speed in km/h for release from controlled braking curve associated with the danger point. A release speed is a speed limit under which the train is allowed to run in the vicinity of the EoA (End of Authority: here routeExit or destinationPoint) when the target speed is zero. One release speed can be associated with the Danger Point.
- <lastSupervisedSectionBeforeDP> – This is the reference to the last TVD section which lies completely before the danger point. It is used when the danger point is situated at the end of a TVD section.
- <situatedAtTrackAsset> – This is the reference to the track asset the danger point is located. It is used when the danger point is situated in the middle of a TVD section or beyond any TVD section in case of not supervised tracks.
