  IfcSurfaceStyleRefraction extends the surface style lighting,

  Currently this includes the refraction index (by which the light ray refracts when passing through a prism) 
  and the dispersion factor (or Abbe constant) which takes into account the wavelength dependency of the refraction.

  \remarks
  If such refraction properties are used, the IfcSurfaceStyle should include within its set of Styles 
  (depending on whether rendering or lighting is used) an instance of IfcSurfaceStyleLighting and IfcSurfaceStyleRefraction, 
  or an instance of IfcSurfaceStyleRendering and IfcSurfaceStyleRefraction.
