  An advanced face is a specialization of a face surface that has to use particular topological 
  and geometric representation items for the definition of the faces, edges and vertices.
  
  - Details -
  An IfcAdvancedFace is restricted to:
  * having a face surface geometry of type IfcElementarySurface, IfcSweptSurface or IfcBSplineSurface;
  * having one IfcFaceOuterBound as the bound of the face, with the exception of closed surfaces;
  * having all faces to be bound by IfcEdgeLoop or IfcVertexLoop;
  * having all edges to have an edge curve geometry;
  * having the edge curve geometry restricted to IfcLine, IfcConic, IfcPolyline, or IfcBSplineCurve;
  
  In case of closed faces with periodic surfaces, such as cylindrical or spherical surfaces, the following applies:
  * the edges of the closed surface, in case of a cylindrical surface the upper and lower cap, refer to the same instance of IfcVertexPoint twice;
  * no IfcFaceOuterBound is provided, or the IfcFaceOuterBound is constructed using an IfcSeamCurve 
    at the periodic end of the underlying closed surface, in case of a cylindrical surface at 0./360. degree;
