 Note that what should be specified on `[TreatReturnedNullStringAs=...]` depends on the spec of each attribute or method.
 
+== `[TreatReturnedNullObjectAs]`(m) == #TreatReturnedNullObjectAs
+
+Summary: `[TreatReturnedNullObjectAs]` controls the behavior when a WebKit null object is returned from the WebCore implementation.
+
+Usage: The possible usage is `[TreatReturnedNullObjectAs=Undefined]`.
+It can be specified on methods that return an object:
+{{{
+    [TreatReturnedNullObjectAs=Undefined] Object func();
+}}}
+
+ * `[TreatReturnedNullObjectAs=Undefined]` indicates that if the returned object is null, the returned value is treated as a JavaScript undefined.
+
+Without `[TreatReturnedNullObjectAs=Undefined]`, if the returned object is null, then the returned value is treated as a JavaScript null.
