Parameters:

id - String; The id of the CrosssSectionElement. Should be unique within the parentLink.

parentLink - CrossSectionLink; Link to which the element belongs.

OTSGeometryException - when creation of the geometry fails

NetworkException - when id equal to null or not unique, or there are multiple slices and the last slice does not end at the length of the design line.
