DSS2 — Service 10.30: Get Dimension Handle Set

The standard does not define what behavior would be expected if a federate were to invoke the Get Dimension Handle Set service on a region specification designator that it got by any other means than creating the region specification itself, or on a region realization designator that it got by any other means than having received it in a conveyed region set. Therefore, it is recommended that text be added to this service prohibiting all other designators as arguments: "There shall be an additional pre-condition to this service that says, "The region was either created by the invoking joined federate using the Create Region Service or it was conveyed to the invoking joined federate in a Set of Sent Region Designators argument." If the region designator specified is not the designator of a region that was either created by the invoking federate or conveyed to it in a Set of Sent Region Designators argument, the "Invalid region" exception shall be generated

Add the suggested new pre-condition.
