Note: There is a newer version of this specification see VEC 2.0.2
A GeometrySegment is the geometric representation of a TopologySegment. A TopologySegment may be represented by more than one GeometrySegments, but only within different BuildingBlockSpecification2D/3D. That means, in a single BuildingBlockSpecification a TopologySegment shall only be represent once (or not).
Furthermore, the definition of the GeometrySegment shall be consistent to the definition in the TopologySpecification. That means, that a GeometrySegment shall have those GeometryNodes as start- & endNode that represent the TopologyNodes referenced from the corresponding TopologySegment.
A GeometrySegment is either a GeometrySegment2D or a GeometrySegment3D.

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