+     * <li>Class-level annotations only affect the class they annotate and
+     * their members, that is, its methods and fields. They never affect a
+     * member declared by a superclass, even if it is not hidden or overridden
+     * by the class in question.
+     * <li>In addition to affecting the annotated class, class-level
+     * annotations may act as a shorthand for member-level annotations. If a
+     * member carries a specific member-level annotation, any annotations of the
+     * same type implied by a class-level annotation are ignored. In other
+     * words, explicit member-level annotations have priority over member-level
+     * annotations implied by a class-level annotation.
+     * <li>The interfaces implemented by a class never contribute annotations
+     * to the class itself or any of its members.
+     * <li>Members inherited from a superclass and which are not hidden or
+     * overridden maintain the annotations they had in the class that declared
+     * them, including member-level annotations implied by class-level ones.
+     * <li>Member-level annotations on a hidden or overridden member are always
+     * ignored.
