Description

Hello!

The Figure 8.10.3.9.A (https://github.com/buildingSMART/IFC4.3.x-development/blob/master/docs/figures/ifcmateriallayerwithoffsets_fig-1.png) shows that IfcMaterialLayerSet for IfcWallType is composed of:
- IfcMaterialLayerSetWithOffset which doesn’t exist in specs;
- IfcMaterialLayerSet which violates 8.10.3.7.5 Formal representation:

I suppose these parts should be as follows:
- IfcMaterialLayerWithOffset
- IfcMaterialLayer
