DSS2 — Service 7.10: Attribute Ownership Unavailable

When a federate receives the Attribute Ownership Unavailable† callback for an instance attribute, it is no longer in the "Willing to Acquire" state with respect to that instance attribute. Therefore, it is permissible for the federate to stop publishing that instance attribute's corresponding class attribute at the known class of the object instance, providing that there are no other corresponding instance attributes at that same known class that the federate is either "Willing to Acquire", or for which the federate has an "Acquisition Pending". If there is at least one other such instance attribute that the federate is "Willing to Acquire" or for which the federate has an "Acquisition Pending", then the federate must be prohibited from unpublishing the corresponding class attribute of that instance attribute at the known class of the object instance.

Change the text of post-condition (b) of this service as suggested.
