 ===== Explicit Argument Names
 
 @AspectJ advice and pointcut annotations have an optional `argNames` attribute that you
-can use to specify the argument names of the annotated method. Note, however, that
+can use to specify the argument names of the annotated method.
-explicit `argNames` will only be used by Spring as a fallback if none of the other
-`ParameterNameDiscoverer` implementations is able to determine parameter names (see the
-previous section for details).
