/** \details
  This entity describes surface members with varying section properties. 
  The properties are provided by means of Pset_StructuralSurfaceMemberVaryingThickness via IfcRelDefinesByProperties, 
  or by means of aggregation: An instance of IfcStructuralSurfaceMemberVarying can be composed 
  of two or more instances of IfcStructuralSurfaceMember with differing section properties. 
  These subordinate members relate to the instance of IfcStructuralSurfaceMemberVarying by IfcRelAggregates.
  
  - Coordinate Systems -
  See definitions at IfcStructuralItem and IfcStructuralSurfaceMember. 
  The local coordinates of an aggregate are generally undefined since continuity of local coordinates of the parts is not ensured.
  
  - Material Use Definition -
  In case of aggregation, only the individual parts (direct instances of IfcStructuralSurfaceMember) 
  carry material and thickness information. Otherwise, definitions at IfcStructuralSurfaceMember apply.
  
  - Property Sets for Objects -
  This concept can be applied to the following resources:
