Parent entity type
Parent express ID
OptionalobjectParent's user-defined name (ObjectType/ElementType/ProcessType), the
USERDEFINED fallback; mirrors IFCDataAccessor.getObjectType. Kept apart
from predefinedType for the raw-token-first match entity-facet.ts uses.
OptionalpredefinedParent's raw PredefinedType token (BEAM, USERDEFINED, …); mirrors getPredefinedTypeRaw.
