  <interface name="Event" id="Events-Event" since="DOM Level 2">
    <descr>
    <p>The <code>Event</code> interface is used to provide contextual information about an event
	to the handler processing the event.  An object which implements the <code>Event</code> interface
	is generally passed as the first parameter to an event handler.  More specific 
	context information is passed to event handlers by deriving additional interfaces from 
	<code>Event</code> which contain information directly relating to the type of event
	they accompany.  These derived interfaces are also implemented by the object passed to the
	event listener.

	Used to specify the time (in milliseconds relative

	<code>timeStamp</code> may be not available for all events. When not
	available, a value of 0 will be returned. Examples of epoch time are
	the time of the system start or 0:0:0 UTC 1st January 1970.

    <method name="stopPropagation" id="Events-Event-stopPropagation">
     <descr>
     <p>The <code>stopPropagation</code> method is used prevent further propagation of an event during
     event flow. If this method is called by any <code>EventListener</code> the event will cease
     propagating through the tree.  The event will complete dispatch to all listeners on the current
     <code>EventTarget</code> before event flow stops.  This method may be used during any stage of
     event flow.</p>

    <method name="preventDefault" id="Events-Event-preventDefault">
     <descr>
     <p>If an event is cancelable, the <code>preventDefault</code> method is used
	 to signify that the event is to be canceled, meaning any default action normally
   taken by the implementation as a result of the event will not occur.  If, during any stage of event flow,
	 the <code>preventDefault</code> method is called the event is canceled.
	 Any default action associated with the event will not occur.  Calling this method
	 for a non-cancelable event has no effect.  Once <code>preventDefault</code> has been
   called it will remain in effect throughout the remainder of the event's propagation.  This
   method may be used during any stage of event flow.

      <descr>
      <p>The <code>initEvent</code> method is used to initialize the value of an <code>Event</code> created through
      the <code>DocumentEvent</code> interface.  This method may only be called before the <code>Event</code> has
      been dispatched via the <code>dispatchEvent</code> method, though it may be called multiple times during that
      phase if necessary.  If called multiple times the final invocation takes precedence.  If called from a
      subclass of <code>Event</code> interface only the values specified in the <code>initEvent</code> method are
      modified, all other attributes are left unchanged.</p>
