024 * Use this to meta-annotate {@code XxxFeature.Require} annotations, so that those annotations can
025 * be used to decide whether to apply a test to a given class-under-test.
026 *
027 * <p>This is needed because annotations can't implement interfaces, which is also why reflection is
028 * used to extract values from the properties of the various annotations.
