As any interested stakeholder filtering objects for a particular purpose
All IFC elements must belong to the appropriate IFC class

* The element "{guid}" is an "{ifc_class}"
* The element "{guid}" is an "{ifc_class}" only
* The element "{guid}" is further defined as a "{predefined_type}"
* The element "{guid}" should not exist because "{reason}"
