   004 | Feature: SWE002 - Mirroring within IfcDerivedProfileDef shall not be used
   005 | 
   006 | The rule verifies that the transformation defined in IfcDerivedProfileDef.Operator does not introduce mirroring.
   007 | The subtype IfcMirroredProfileDef should be used for that. For the tapered sweeps, which tend to rely on
   008 | IfcDerivedProfileDef, by expressing the tapering operation as a change in profile, mirroring should not be used
   009 | altogether.
   010 | 
   011 |   Scenario: IfcDerivedProfileDef must not use mirroring as there is a dedicated subtype for that
