+
+Modifying Functions
+-------------------
+
+.. _modify-argument:
+
+modify-argument
+^^^^^^^^^^^^^^^
+
+    The modify-argument node specifies which of the given function's arguments the
+    modification affects, and is a child of the modify-function node. Use the
+    remove-argument, replace-default-expression, remove-default-expression,
+    replace-type, reference-count and define-ownership nodes to specify the details
+    of the modification.
+
+    .. code-block:: xml
+
+         <modify-function>
+             <modify-argument index="return | this | 1 ..." >
+                 // modifications
+             </modify-argument>
+         </modify-function>
+
+    Set the ``index`` attribute to "1" for the first argument, "2" for the second
+    one and so on. Alternatively, set it to "return" or "this" if you want to
+    modify the function's return value or the object the function is called upon,
+    respectively.
+
+.. _remove:
+
+remove
+^^^^^^
+
+    The remove node removes the given method from the generated target language
+    API, and it is a child of the modify-function node.
+
+    .. code-block:: xml
+
+         <modify-function>
+             <remove class="all" />
+         </modify-function>
+
+    .. warning:: This tag is deprecated, use the ``remove`` attribute from :ref:`modify-function` tag instead.
+
+.. _access:
+
+access
+^^^^^^
+
+    The access node changes the access privileges of the given function in the
+    generated target language API, and it is a child of the modify-function node.
+
+    .. code-block:: xml
+
+        <modify-function>
+            <access modifier="public | protected | private"/>
+        </modify-function>
+
+    .. warning:: This tag is deprecated, use the ``access`` attribute from :ref:`modify-function` tag instead.
+
+.. _rename:
+
+rename
+^^^^^^
+
+    The rename node changes the name of the given function in the generated target
+    language API, and it is a child of the modify-function node.
+
+    .. code-block:: xml
+
+        <modify-function>
+            <rename to="..." />
+        </modify-function>
+
+    The ``to`` attribute is the new name of the function.
+
+    .. warning:: This tag is deprecated, use the ``rename`` attribute from :ref:`modify-function` tag instead.
