IFC task-type enum — union of IFC4 and IFC4X3
IfcTaskTypeEnumvalues.IFC4 introduced the first 14. IFC4X3 added 9 more to cover the operations/maintenance lifecycle (ADJUSTMENT through TROUBLESHOOTING). The superset is exposed here so scripts can author schedules for either schema; IFC4 files that try to round-trip the newer values may fail validation on strict toolchains — caller's responsibility.
