   TAggrMOErrorStatus ::= TEXTUAL-CONVENTION
     STATUS       current
     DESCRIPTION
       "This data type is used to model the error status of the
        sampled MO instance.  The error status for a sampled MO
        instance is given in terms of two elements:
          o The moIndex, which indicates the sample number of the MO
            instance (starting at 1) in the value of the time-
            aggregated MO instance.
          o The moError, which indicates the error that was
            encountered in sampling that MO instance.
        The syntax in ASN.1 Notation will be
        ErrorStatus :: = SEQUENCE {
           moIndex  Integer32,
           moError  SnmpPduErrorStatus
        }
        TAggrMOErrorStatus ::= SEQUENCE OF {
           ErrorStatus
        }
        Note1: The command responder will supply values for all
               the samples of the MO instance.  If an error is
               encountered for a sample, then the corresponding
               value will have an ASN.1 value NULL, and an error
               will be flagged in the corresponding
               TAggrMOErrorStatus object.
               Only MOs for which errors have been encountered will
               the corresponding moIndex and moError values be set.
        Note2: The error code for the component MO instances will be
               in accordance with the SnmpPduErrorStatus TC defined
               in the DISMAN-SCHEDULE-MIB[RFC3231].

        Note: The command generator will need to know the
              constituent MO instance and the sampling interval to
              correctly interpret TimeAggrMOValue.
