+        Set the value of a stanza interface using dictionary-like syntax.
+
+        Example:
+            >>> msg['body'] = "Hi!"
+            >>> msg['body']
+            'Hi!'
+
+        Stanza interfaces are typically mapped directly to the underlying XML
+        object, but can be overridden by the presence of a setAttrib method
+        (or setFoo where the interface is named foo, etc).
+
+        The effect of interface value assignment for an interface
+        named 'foo' will be one of:
+            1. Delete the interface's contents if the value is None.
+            2. Call setFoo, if it exists.
+            3. Set the text of a foo element, if foo is in sub_interfaces.
+            4. Set the value of a top level XML attribute name foo.
+            5. Attempt to pass value to a plugin named foo using the plugin's
+               foo interface.
+            6. Do nothing.
+
+        Arguments:
+            attrib -- The name of the stanza interface to modify.
+            value  -- The new value of the stanza interface.
