+ * Base class that provides a common interface for publishing events. Subclasses are expected to to have a property
+ * "events" with all the events defined, and, optionally, a property "listeners" with configured listeners defined.

  * For example:
- * <pre><code>
-Ext.define('Employee', {
-    extend: 'Ext.util.Observable',
-    constructor: function(config){
-        this.name = config.name;
-        this.addEvents({
-            "fired" : true,
-            "quit" : true
-        });
-
-        // Copy configured listeners into *this* object so that the base class&#39;s
-        // constructor will add them.
-        this.listeners = config.listeners;
-
-        // Call our superclass constructor to complete construction process.
-        Employee.superclass.constructor.call(this, config)
-    }
-});
-</code></pre>
- * This could then be used like this:<pre><code>
-var newEmployee = new Employee({
-    name: employeeName,
-    listeners: {
-        quit: function() {
-            // By default, "this" will be the object that fired the event.
-            alert(this.name + " has quit!");
-        }
-    }
-});
-</code></pre>
+ *
+ *     Ext.define('Employee', {

+     * This object may contain any of the following properties:
+     *
+     * - **scope** : Object
+     *
+     *   The scope (`this` reference) in which the handler function is executed. **If omitted, defaults to the object
+     *   which fired the event.**
+     *
+     * - **delay** : Number
+     *
+     *   The number of milliseconds to delay the invocation of the handler after the event fires.
+     *
+     * - **single** : Boolean
+     *
+     *   True to add a handler to handle just the next firing of the event, and then remove itself.
+     *
+     * - **buffer** : Number
+     *
+     *   Causes the handler to be scheduled to run in an {@link Ext.util.DelayedTask} delayed by the specified number of
+     *   milliseconds. If the event fires again within that time, the original handler is _not_ invoked, but the new
+     *   handler is scheduled in its place.
+     *
+     * - **target** : Observable
+     *
+     *   Only call the handler if the event was fired on the target Observable, _not_ if the event was bubbled up from a
+     *   child Observable.
+     *
+     * - **element** : String
+     *
+     *   **This option is only valid for listeners bound to {@link Ext.Component Components}.** The name of a Component
+     *   property which references an element to add a listener to.
+     *
+     *   This option is useful during Component construction to add DOM event listeners to elements of
+     *   {@link Ext.Component Components} which will exist only after the Component is rendered.
+     *   For example, to add a click listener to a Panel's body:
+     *
+     *       new Ext.panel.Panel({
+     *           title: 'The title',
+     *           listeners: {
+     *               click: this.handlePanelClick,
+     *               element: 'body'
+     *           }
+     *       });
+     *
+     * **Combining Options**
+     *
+     * Using the options argument, it is possible to combine different types of listeners:
+     *
      * A delayed, one-time listener.
-     * <pre><code>
-myPanel.on('hide', this.handleClick, this, {
-single: true,
-delay: 100
-});</code></pre>
-     * <p>
-     * <b>Attaching multiple handlers in 1 call</b><br>
-     * The method also allows for a single argument to be passed which is a config object containing properties
-     * which specify multiple events. For example:<pre><code>
-myGridPanel.on({
-    cellClick: this.onCellClick,
-    mouseover: this.onMouseOver,
-    mouseout: this.onMouseOut,
-    scope: this // Important. Ensure "this" is correct during handler execution
-});
