Attributes:
- belongsToParent: reference to a parent under crossing
- if some information exists in parent and child, then information in child overwrites it in child
- if some information exists only in parent, then child inherits this information from parent (optional; xs:string; patterns: (urn:uuid:)?[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}|{[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}}),
- constructionType: construction type of under crossing: bridge or tunnel (obligatory;
xs:string; patterns: other:w{2,})
- Possible values:
- bridge: a structure built to span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the way underneath [wikipedia].
- tunnel: underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end [wikipedia].
- movableBridge: A special movable bridge (undercrossing) which is used for railway traffic passing a waterway underneath the railway line in normal position but allows for temporarily being moved out of the way of the vessels. It is then not passable by trains.
The normal position is locked and supervised by interlocking system. The other control of the bridge is outside the interlocking system.,
- verbalConstraint: verbal formulation for any kind of further constraint that applies for using the overCrossing or underCrossing (optional;
xs:string),
- id: the identifier of the object; this can be either of type xs:ID or UUID (obligatory;
xs:string; patterns: (urn:uuid:)?[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}|{[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}}); 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.
