Description
MaterialLayerSet has MaterialLayers | LIST [1:?] OF IfcMaterialLayer
MaterialProfileSet has MaterialProfiles | LIST [1:?] OF IfcMaterialProfile
MaterialConstituentSet has MaterialConstituents | OPTIONAL SET [1:?] OF IfcMaterialConstituent
Why are constituents special? Why does it have optionality? What should the correct cardinality be?
Edit: to clarify I'm only asking about optionality. The list vs set makes total sense.
