Research direction

No source file or test is named. Reproduce an IFC2X3 export with the parameter mapping table on Revit 2024.3.x and IFC for Revit 24.3.2, then trace the export mapping for brandwerendheid and Pset_WallCommon.FireRating. Done means the mapping table correctly maps the Revit parameter to the IFC common property.
