Name Type Mult. Description Owning Classifier
identification String 1

Specifies a unique identification of the GeometryNode. The identification is guaranteed to be unique within the corresponding BuildingBlockSpecification. Over all VEC-documents a GeometryNode-instance can be trusted to be the same if the BuildingBlockSpecification-instance is the same (see BuildingBlockSpecification) and the identification of the GeometryNode is the same.

aliasId AliasIdentification 0..*

Specifies additional identifiers for the GeometryNode.
