+ * <code>BeanContextEvent</code> is the abstract root event class
+ * for all events emitted
+ * from, and pertaining to the semantics of, a <code>BeanContext</code>.
+ * This class introduces a mechanism to allow the propagation of
+ * <code>BeanContextEvent</code> subclasses through a hierarchy of
+ * <code>BeanContext</code>s. The <code>setPropagatedFrom()</code>
+ * and <code>getPropagatedFrom()</code> methods allow a
+ * <code>BeanContext</code> to identify itself as the source
+ * of a propagated event.
