Comment(by strk):

 With r8613 we have the concept of empty TopoGeometry objects.
 They do have an ID but no entry in relation table.
 Basically their construction only increments the sequence.
 You can create them by omitting the components parameter to
 CreateTopoGeom.
 Under the hood, the CreateTopoGeom function skips from the given array any
 TopoElement with type=0 (and expects id=0 as well).
