DSS2 — Service 9.10: Subscribe Interaction Class With Regions: passive indicator

This service description should be clarified regarding the intended use of the optional passive subscription indicator. The text does not explain what it means for a subscription with region to be passive or active. It is recommended that clarifying text be added that indicates that the intent is for invocations of the Subscribe Interaction Class With Regions service for any given interaction class to be cumulative with respect to the set of subscribed regions of a given interaction class, but substitutive with respect to whether each (interaction class, region) pair is subscribed actively or passively. If the current invocation of the Subscribe Interaction Class With Regions service includes a given (interaction class, region) subscription that already exists, the property of active versus passive for that (interaction class, region) subscription is substituted according to the value (or absence) of the optional passive subscription indicator argument to the current invocation of the Subscribe Interaction Class With Regions service.

Add text explaining the use of the optional passive subscription indicator.
