Reference to empty / non-existant table

https://forums.buildingsmart.org/t/how-to-find-the-full-text-of-a-concept-usage-excerpt-in-an-ifc-specification/4783/2

Start with the linked forum discussion to determine which IFC concept usage excerpt and table are being referenced, then locate that reference in the IFC4.x specification sources. Done means the reference is corrected to an existing table or the missing details are documented clearly enough to identify the required change.
