    1.31 +/**
    1.32 + * Indicates the kinds of program element to which an annotation type
    1.33 + * is applicable.  If a Target meta-annotation is not present on an
    1.34 + * annotation type declaration, the declared type may be used on any
    1.35 + * program element.  If such a meta-annotation is present, the compiler
    1.36 + * will enforce the specified usage restriction.
    1.37 + *
    1.38 + * For example, this meta-annotation indicates that the declared type is
    1.39 + * itself a meta-annotation type.  It can only be used on annotation type
    1.40 + * declarations:
    1.41 + * <pre>
    1.42 + *    &#064;Target(ElementType.ANNOTATION_TYPE)
    1.43 + *    public &#064;interface MetaAnnotationType {
    1.44 + *        ...
    1.45 + *    }
    1.46 + * </pre>
    1.47 + * This meta-annotation indicates that the declared type is intended solely
    1.48 + * for use as a member type in complex annotation type declarations.  It
    1.49 + * cannot be used to annotate anything directly:
    1.50 + * <pre>
    1.51 + *    &#064;Target({})
    1.52 + *    public &#064;interface MemberType {
    1.53 + *        ...
    1.54 + *    }
    1.55 + * </pre>
    1.56 + * It is a compile-time error for a single ElementType constant to
    1.57 + * appear more than once in a Target annotation.  For example, the
    1.58 + * following meta-annotation is illegal:
    1.59 + * <pre>
    1.60 + *    &#064;Target({ElementType.FIELD, ElementType.METHOD, ElementType.FIELD})
    1.61 + *    public &#064;interface Bogus {
    1.62 + *        ...
    1.63 + *    }
    1.64 + * </pre>
