 * This QoS policy should be used in combination with the OWNERSHIP policy. It only applies to the situation case where
 * OWNERSHIP kind is set to EXCLUSIVE.
 *
 * The value of the OWNERSHIP_STRENGTH is used to determine the ownership of a data-instance (identified by the
 * key). The arbitration is performed by the DataReader. The rules used to perform the arbitration are described in
 * Section 7.1.3.9.2, "EXCLUSIVE kind", on page 112.
