     Type:  defect    |      Status:  new          
 Priority:  medium    |   Milestone:  PostGIS 2.0.0
Component:  topology  |     Version:  trunk

 The SQL/MM document says that an exception should be raised IF the face
 argument references an unknown face. Doesn't say anything about faces
 bound by no ring (would be due to invalid topology).

 The current implementation results in an exception in the latter case (no
 ring) but not in the former (unknown face).

 In turn this doesn't help validating a topology in that the exception on
 invalid topology makes the whole validateTopology function bail out.
