+/**
+ * Indicates the kinds of program element to which an annotation type
+ * is applicable.  If a Target meta-annotation is not present on an
+ * annotation type declaration, the declared type may be used on any
+ * program element.  If such a meta-annotation is present, the compiler
+ * will enforce the specified usage restriction.
+ *
+ * For example, this meta-annotation indicates that the declared type is
+ * itself a meta-annotation type.  It can only be used on annotation type
+ * declarations:
+ * <pre>
+ *    &#064;Target(ElementType.ANNOTATION_TYPE)
+ *    public &#064;interface MetaAnnotationType {
+ *        ...
+ *    }
+ * </pre>
+ * This meta-annotation indicates that the declared type is intended solely
+ * for use as a member type in complex annotation type declarations.  It
+ * cannot be used to annotate anything directly:
+ * <pre>
+ *    &#064;Target({})
+ *    public &#064;interface MemberType {
+ *        ...
+ *    }
+ * </pre>
+ * It is a compile-time error for a single ElementType constant to
+ * appear more than once in a Target annotation.  For example, the
+ * following meta-annotation is illegal:
+ * <pre>
+ *    &#064;Target({ElementType.FIELD, ElementType.METHOD, ElementType.FIELD})
+ *    public &#064;interface Bogus {
+ *        ...
+ *    }
+ * </pre>
