+ * Indicates that the named compiler warnings should be suppressed in the
+ * annotated element (and in all program elements contained in the annotated
+ * element).  Note that the set of warnings suppressed in a given element is
+ * a superset of the warnings suppressed in all containing elements.  For
+ * example, if you annotate a class to suppress one warning and annotate a
+ * method to suppress another, both warnings will be suppressed in the method.
+ * However, note that if a warning is suppressed in a {@code
+ * module-info} file, the suppression applies to elements within the
+ * file and <em>not</em> to types contained within the module.
+ *
+ * <p>As a matter of style, programmers should always use this annotation
+ * on the most deeply nested element where it is effective.  If you want to
+ * suppress a warning in a particular method, you should annotate that
+ * method rather than its class.
