 <p>DOM Events is designed with two main goals. The first goal is the design of an <a href='#glossary-dt-event'>event</a> system which allows registration of event listeners and describes event flow through a tree structure. Additionally, the specification will provide standard modules of events for user interface control and document mutation notifications, including defined contextual information for each of these event modules.</p>

The interface allows registration and removal of event listeners, and dispatch of events to an event target.</p>
+<p>When used with the <a href='#events-Events-flow'>DOM event flow</a>, this interface is implemented by all <a href='#glossary-dt-target-node'>target nodes</a> and target ancestors, i.e. all DOM <code>Nodes</code> of the tree support this interface when the implementation conforms to DOM Level 3 Events and, therefore, this interface can be obtained by using binding-specific casting methods on an instance of the <code>Node</code> interface.</p>
 <p>Invoking <code>addEventListener</code> or <code>addEventListenerNS</code> repeatedly on the same <code>EventTarget</code> with the same values for the parameters <code>namespaceURI</code>, <code>type</code>, <code>listener</code>, and <code>useCapture</code> has no effect. Doing so does not cause the <a href='#events-Events-EventListener'><code>EventListener</code></a> to be called more than once and does not cause a change in the triggering order. In order to register a listener for a different event group (<a href='#events-Event-groups'>Event groups</a>) the previously registered listener has to be removed first.</p>
