/**
 * Annotation that specifies that an element is experimental and may change
 * without notice.
 * <p>
 * Clients that visualize Flight Recorder events should <em>not</em> show the
 * events or fields annotated with the {@code Experimental} annotation by
 * default. This annotation allows event producers the freedom to try out new
 * events without committing to them.
 * <p>
 * Clients may provide a check box (for example, in a preference page) where a
 * user can opt-in to display experimental data. If the user decide to do so,
 * the user interface should mark experimental events or fields so users can
 * distinguish them from non-experimental events.
 * <p>
 * This annotation is inherited.
