/**
 * Indicates the contexts in which an annotation interface is applicable. The
 * declaration contexts and type contexts in which an annotation interface may
 * be applicable are specified in JLS {@jls 9.6.4.1}, and denoted in source code by
 * enum constants of {@link ElementType java.lang.annotation.ElementType}.
 *
 * <p>If an {@code @Target} meta-annotation is not present on an annotation
 * interface {@code T}, then an annotation of type {@code T} may be written as
 * a modifier for any declaration.
 *
 * <p>If an {@code @Target} meta-annotation is present, the compiler will enforce
 * the usage restrictions indicated by {@code ElementType}
 * enum constants, in line with JLS {@jls 9.7.4}.
 *
 * <p>For example, this {@code @Target} meta-annotation indicates that the
 * declared interface is itself a meta-annotation interface.  It can only be
 * used on annotation interface declarations:
 * <pre>
 *    &#064;Target(ElementType.ANNOTATION_TYPE)
 *    public &#064;interface MetaAnnotationType {
 *        ...
 *    }
 * </pre>
 *
 * <p>This {@code @Target} meta-annotation indicates that the declared class or
 * interface is intended solely for use as a member class or interface in
 * complex annotation interface declarations.  It cannot be used to annotate
 * anything directly:
 * <pre>
 *    &#064;Target({})
 *    public &#064;interface MemberInterface {
 *        ...
 *    }
 * </pre>
 *
 * <p>It is a compile-time error for a single {@code ElementType} constant to
 * appear more than once in an {@code @Target} annotation.  For example, the
 * following {@code @Target} meta-annotation is illegal:
 * <pre>
 *    &#064;Target({ElementType.FIELD, ElementType.METHOD, ElementType.FIELD})
 *    public &#064;interface Bogus {
 *        ...
 *    }
 * </pre>
 *
 * @since 1.5
 * @jls 9.6.4.1 @Target
 * @jls 9.7.4 Where Annotations May Appear
 * @jls 9.7.5 Multiple Annotations of the Same Interface
