DSS2 — Get Range Bounds: created or conveyed

The standard does not define what behavior would be expected if a federate were to invoke the Get Range Bounds 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: "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.
