The <Component > Object has the ModellingRule OptionalPlaceholder and represents the identifiable components of a Machine. As any ObjectType can be used for components, it is of BaseObjectType. As all identifiable components shall contain the Identification Object, <Component> references to that AddIn as defined in Table 26. As a Machine can contain other Machines, it does not reference to the MachineryComponentIdentificationType, but the MachineryItemIdentificationType, which is the abstract supertype of MachineryComponentIdentificationType and MachineIdentificationType.
