   Priority:  major          |   Milestone:  3.7.0                  
  Component:  FDO API        |     Version:  3.7.0                  
   Severity:  2              |    Keywords:  FdoILinearRing 2 points
External_id:                 |  
-----------------------------+----------------------------------------------
 The FdoILinearRing constructor, that takes a set of ordinates, succeeds as
 long as the ordinates define at least one point. However, the construct
 that takes a Direction Position collection requires at least 3 positions.
 This constructor should change, to accept collections with 1 or 2
 positions, to be consistent with the constructor for ordinates.

 Although rings, with < 3 points, are not topologically correct, they can
 occur in existing data sets and need to be loadable into FDO Geometries.
