+/**
+ * @ngdoc directive
+ * @name ng.directive:ngOpen
+ * @restrict A
+ *
+ * @description
+ * The HTML specs do not require browsers to preserve the special attributes such as open.
+ * (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 `ngMultiple` directive.
+ *
+ * @example
+     <doc:example>
+       <doc:source>
+         Check me check multiple: <input type="checkbox" ng-model="open"><br/>
+         <details id="details" ng-open="open">
+            <summary>Show/Hide me</summary>
+         </details>
+       </doc:source>
+       <doc:scenario>

+           input('open').check();
+           expect(element('#details').prop('open')).toBeTruthy();
