This attribute specifies the expected Nams Identifier of the module
to which this DpnGateway is connected. The DpnGateway end
points exchange their Nams Identifiers through the DpnGateway's
staging protocol. The staged value is validated and the
remoteValidationAction will be executed for those values not
matching the value supplied for this attribute.
If this value is zero, then the comparison is always successful.
