+The concept `TriangulationDSCellBase_3` describes the requirements for
+the cell base class of a `CGAL::Triangulation_data_structure_3<Vb,Cb>`.
+
+Note that if the `CGAL::Triangulation_data_structure_3`
+is plugged into a triangulation class,
+the face base class may have additional geometric
+requirements depending on the triangulation class.
