This Data Type enumerates the choices for the Reason attribute of the Response element defined in the FBMGT DTD and subclause 6.4 of the Compliance Profile for Feasibility Demonstrations. It includes an initial OK item for the #IMPLIED value specified in the DTD, and three additional items (NULL_POINTER, INTERRUPTED, UNKNOWN) to provide more detailed reporting of exception conditions encountered during management command processing.

When used as the Reason component of the structured type MGT_RSP, this requires only a single byte for ASN.1 encoding, versus, for example, the 18 bytes required to encode the STRING value of the XML declaration Reason="NOT_READY" .

• This encoding does require one extra byte vs. the STRING-encoded XML for the case of MGT_REASON#OK, where the XML does not include a Reason attribute. However, the combination of the ID and Reason attributes of a MGT_RSP variable only requires 5 bytes in total, where a minimum of 6 bytes are required for the STRING-encoded XML equivalent, e.g., ID="1" .
