   005 | Feature: GEM011 - Curve segments consistency
   006 | 
   007 |   The rule verifies that the same entity type is used for all segments
   008 |   and that IfcCurveSegment is used with IfcSegmentedReferenceCurve and IfcGradientCurve
   009 |   The rule is identical to ALS011, except that it does not require the presence of an IfcAlignment.
