Hello everyone,

We identified some mistake/missing for some Pset in the latest schema (IFC4x3 RC2).

In order to solve them asap during the schema development process please find below our proposal for the **scope** of following Psets that are badly defined:

Pset\_RoadDesignCriteriaCommon : IfcRoad ;IfcReferent  
Pset\_SumpBusterCommon : IfcSign  
Pset\_Superelevation : IfcRoad ;IfcReferent  
Pset\_TrafficCalmingDeviceCommon : IfcElementAssembly

Let me know your feedback about this.

Kevin.
