   006 | Feature: ALS011 - Alignment segment entity type consistency
   007 | 
   008 |   The rule verifies that the same entity type is used for all segments
   009 |   and that IfcCurveSegment is used with IfcSegmentedReferenceCurve and IfcGradientCurve
   010 |   The rule is similar to GEM011, except that it requires the presence of an IfcAlignment.
