| bValid | Boolean | Returned value indicates if the key datatype is valid and compatible with the reference datatype. If True, the key datatype is valid and compatible with the reference datatype. If False, the key datatype is either not valid or not compatible with the reference datatype. |
| idKeyDatatype | Identifier | Name of the key datatype |
| idReferenceDatatype | Identifier | Name of the reference datatype |
