  *     then special attribute "disabled" will be set on the element

+ /**
+ * @ngdoc directive
+ * @name ng.directive:ngEnabled
+ * @restrict A
+ *
+ * @description
+ *
+ * The following markup will make the button enabled on Chrome/Firefox but not on IE8 and older IEs:
+ * <pre>
+ * <div ng-init="scope = { isDisabled: false }">
+ *  <button disabled="{{scope.isDisabled}}">Disabled</button>
+ * </div>
+ * </pre>
+ *
+ * The HTML specs do not require browsers to preserve the values of special attributes
+ * such as disabled. (The presence of them means true and absence means false)
+ * This prevents the Angular compiler from correctly retrieving the binding expression.
+ * To solve this problem, we introduce the `ngDisabled` directive and its corollary `ngEnabled`.
+ *
+ * @example
+    <doc:example>
+      <doc:source>
+        Click me to toggle: <input type="checkbox" ng-model="checked"><br/>
+        <button ng-model="button" ng-enabled="checked">Button</button>
+      </doc:source>

+          expect(element('.doc-example-live :button').prop('disabled')).toBeTruthy();
+          input('checked').check();
+          expect(element('.doc-example-live :button').prop('disabled')).toBeFalsy();
