+/** Components can implement <code>XUnloadingPreference</code> in order to indicate
+    how they should be treated when their hosting library is to be unloaded.
+
+   When someone calls <code>rtl_unloadUnusedModules</code> then the unloading
+    listeners are notified by calling previously registered callback
+    functions. A listener is an entity that employs, registers, and
+    unregisters the callback functions on its behalf. Upon notification
+    (the callback function is being called)
+    a listener may release references to UNO components. Thus, the
+    loaded libraries can be unloaded, if no one else keeps any
+    objects from the library alive. <br>
+    Before a listener releases references, it should ask for this interface.
+    If the interface is not implemented, then the listener may release the
+    object; otherwise, it calls <code>releaseOnNotification</code>. If the function
+    returns false then the listener should keep the reference, otherwise
+    it may release it.
