Cause: A locator path for an attribute was invalid.
Action: Please verify the locator path is properly constructed. All attribute used in the locator path must be defined in the DICOM standard and must not be retired. An attribute that is not the last one of the locator path must be a sequence type. If the locator path is correct, please verify the DICOM data dictionary is up-to-date. If the data dictionary is obsolete, please use the ORD_DICOM_ADMIN API to update the data dictionary.
