@Documented
@Retention(RUNTIME)
@Target(ANNOTATION_TYPE)
public @interface Documented
If the annotation @Documented is present on the declaration
 of an annotation type A, then any @A annotation on
 an element is considered part of the element's public contract.
 In more detail, when an annotation type A is annotated with
 Documented, the presence and value of annotations of type
 A are a part of the public contract of the elements A
 annotates.
 Conversely, if an annotation type B is not
 annotated with Documented, the presence and value of
 B annotations are not part of the public contract
 of the elements B annotates.
 Concretely, if an annotation type is annotated with 
 Documented, by default a tool like javadoc will display
 annotations of that type in its output while annotations of
 annotation types without Documented will not be displayed.
