       /**
        * A view class that is used for creating XML responses.
+       *
        * By setting the '_serialize' key in your controller, you can specify a view variable
        * that should be serialized to XML and used as the response for the request.
        * This allows you to omit views + layouts, if your just need to emit a single view
        * variable as the XML response.
+       *
        * In your controller, you could do the following:
+       *
        * `$this->set(array('posts' => $posts, '_serialize' => 'posts'));`
+       *
        * When the view is rendered, the `$posts` view variable will be serialized
        * into XML.
+       *
        * **Note** The view variable you specify must be compatible with Xml::fromArray().
+       *
        * You can also define `'_serialize'` as an array. This will create an additional
        * top level element named `<response>` containing all the named view variables:
+       *
        * ```
        * $this->set(compact('posts', 'users', 'stuff'));
        * $this->set('_serialize', array('posts', 'users'));
        * ```
+       *
        * The above would generate a XML object that looks like:
+       *
        * `<response><posts>...</posts><users>...</users></response>`
+       *
        * If you don't use the `_serialize` key, you will need a view. You can use extended
        * views to provide layout like functionality.
+       *
