+ * <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
