+/** the server-side interface to a weak object.
+
+
+
+    <p>This interface is proxy to the adapted object.
+    In order to make it possible to have weak references to objects,
+    the XAdapter interface must be implemented to provide
+    a weak adapter for the clients.
+
+    <h4>Concept of weak referencing:</h4>
+
+    </p>
+    <p>This module specifies the interfaces for implementing and using
+    weak references.</p>
+    <p>
+
+    </p>
+    <p>The sense of weak references is to hold a reference to an object
+    without affecting the lifetime of the object. That means that a weak
+    reference may become invalid, at any time, if the referenced object dies.
+
+    </p>
+    <p>The following interfaces describe one way to handle weak references
+    by providing a weak adapter. The weak object has to provide this
+    adapter if anyone wants to hold a weak reference. To separate their
+    lifetimes, the adapter and the original object must not share the same
+    reference counter.  The weak reference is in fact only a hard reference
+    to the adapter, which knows - but does not hold - the original object.
+    That means that the implementation and synchronization of weak
+    referencing is the responsibility of the object.  The following
+    interfaces are involved in the concept of weak referencing:
+
+    <dl>
+    <dt>
+    XWeak
+    </dt>
+    <dd>is the server-side interface of the referred object. This
+    referred object must support the XAdapter interface.
+
+    </dd>
+    <dt>
+    XReference
+    </dt>
+    <dd>is a client-side interface which must be implemented by
+    the holder of any weak reference. It is used for notification
+    when the adapted object dies.
+
+    </dd>
+    </dl>
+    </p>
+ */
+published interface XWeak: com::sun::star::uno::XInterface
+{
+    /** queries the weak adapter.
+
+
+
+        <p>It is important that the adapter must know, but not hold
+        the adapted object. If the adapted object dies, all references
+        to the adapter have to be notified to release the adapter.
+
+        </p>
