    Function checkEntityFacet

    • Check if an entity matches an entity facet

      Deliberately exact-match, not subtype-aware: buildingSMART's IDS spec is explicit that entity facet matching has no automatic inheritance — Documentation/UserManual/entity-facet.md (buildingSMART/IDS) says "There is no automatic inheritance in IDS entity facet interpretation. In other words, all the entities need to be listed explicitly. […] to create a requirement applicable to all IfcElement objects, one should list all IfcElement sub-entities, such as IfcWall, IfcDoor, etc. Also, the IfcElement should not be listed, as it is an abstract entity […] and would not appear in a model." Do not "fix" this into a descendant-closure match the way @ifc-lite/parser's expandTypes (a different, non-IDS query surface) does — that would make this checker non-conformant.
