+     This functions appends a sibling to an existing node.
+     The child can be created with e.g.
+     <function>DomDocument_create_element</function>,
+     <function>DomDocument_create_text</function> etc. or simply by using any
+     other node.
+    </para>
+    <para>
+     Before a new sibling is added it is first duplicated. Therefore the new
+     child is a completely new copy which can be modified without changing the
+     node which was passed to this function. If the node passed has children
+     itself, they will be duplicated as well, which makes it quite easy to
+     duplicate large parts of a xml document. The return value is the
+     added sibling. If you plan to do further modifications on the added
+     sibling you must use the returned node.

+     This function has been added to provide the behaviour of
+     <function>DomNode_append_child</function> as it works till PHP 4.2.
