DSS2 — Service 7.9: Attribute Ownership Acquisition If Available: self-transition

As currently specified, it is not clear what should happen if a federate invokes the Attribute Ownership Acquisition If Available service for an instance attribute that is already in the "Willing to Acquire" state. Text should be added that clarifies that if a federate invokes the Attribute Ownership Acquisition If Available service for an instance attribute that is already in the "Willing to Acquire" state, that instance attribute's state shall remain unchanged. In other words, if a federate invokes the Attribute Ownership Acquisition If Available service for an instance attribute that is in the "Willing to Acquire" state, that instance attribute shall continue to be in the "Willing to Acquire" state. If there are additional instance attributes in the attribute set that is an argument to the Attribute Ownership Acquisition If Available service, those instance attributes shall enter the "Willing to Acquire" state, assuming that they meet all of the pre-conditions of the Attribute Ownership Acquisition If Available service and they are not already in the "Willing To Acquire" state.

Add the suggested clarifying text.
