DSS2 — Section 11.4.1: Normal RTI MOM administration: null values

Some parameter definitions in Table 17 indicate that under certain circumstances the value of a MOM interaction parameter shall be null. For example, according to Table 17, if the specified service does not normally return a value, then the HLAreturnedArgument parameter of the HLAmanager.HLAfederate.HLAreport.HLAreportServiceInvocation interaction shall be null. Also, if the value of the HLAsuccessIndicator parameter of the HLAmanager.HLAfederate.HLAreport.HLAreportServiceInvocation interaction is HLAtrue, then the value of the HLAexception parameter shall be null. By "null" the text should make clear that the expectation is that the parameter/value pair set will be present in the interaction, but the value will be an empty (zero-length) array.

Clarify the meaning of the term “null”, as suggested.
