 This is often not what you want to do.
 
-In most cases, you will want to annotate the individual methods.
+If you want to use `@AuthorizeReturnObject` on a class or interface whose methods return value types, like `int`, `String`, `Double` or collections of those types, then you should also publish the appropriate `AuthorizationAdvisorProxyFactory.TargetVisitor` as follows:
