+### In IFC2X3 an entity name resolves via the type mapping table 1/2
+
+The [IFC2X3 occurrence and type mapping table](../ifc2x3-occurrence-type-mapping-table.md)
+lets an IFC2X3 model be checked with the IFC4 entity name `IfcAirTerminal`
+even though that class does not exist in IFC2X3. Applicability matches the
+real IFC2X3 occurrence class `IfcFlowTerminal`, and the requirement checks
+that it is typed by `IfcAirTerminalType`.

+### In IFC2X3 an entity name resolves via the type mapping table 2/2

+Same specification as the case above, run against an `IfcFlowTerminal`
+typed by `IfcElectricApplianceType` instead, so a false pass could not be
+mistaken for a correctly-checked type mismatch.
