+/** Objects which implement this interface can become aggregates of
+    a delegator.
+
+    <p>That means if an object "A" aggregates "B", "A" can provide all
+    or some of the interfaces of "B". Whenever the method
+    XInterface::queryInterface()
+    is called on either of the objects, the call will be forwarded
+    to object "A". Object "A" now can determine whether to use the
+    interfaces of "A" or "B" or neither. Actually, any number of
+    aggregates can be used, even nested ones (aggregated objects which are
+    delegators by themselves).
+
+    <p>The following rules are to be observed:
+    <ol>
+    <li>All calls to XInterface::acquire()
+    which are made before the delegator was set (using the method
+    XAggregation::setDelegator()) must not be taken back
+    (using the method XInterface::release())
+    before the delegation is removed by calling
+    <code>xAggregation-&gt;setDelegator(NULL)</code>.
+
+    <li>The constructor of a delegator has to increment its
+    own reference count by calling its method
+    XInterface::acquire()
+    before it sets itself to any aggregate using the method
+    XAggregation::setDelegator(). After that
+    call it has to reset its own reference count without the
+    destructor getting called.
+
+    <li>The destructor of a delegator has to reset the delegator in
+    its aggregated objects by calling their method
+    XAggregation::setDelegator() with
+    NULL before it releases its reference to
+    its aggregated objects.
+    </ol>
+
+    @deprecated
+    Aggregation will no longer be supported as a high-level concept of UNO.
+    You may still have the option to implement a UNO object consisting of
+    several single objects in your specific programming language, though this
+    depends on your programming language.
