-/**
- * The `auto-binding-dart` element extends the template element. It provides a
- * quick and easy way to do data binding without the need to setup a binding
- * delegate or use the [templateBind] call. Both data and event handlers can be
- * bound using the [model].
- *
- * The `auto-binding-dart` element acts just like a template that is bound to
- * a model. It stamps its content in the dom adjacent to itself. When the
- * content is stamped, the `template-bound` event is fired.
- *
- * **NOTE**: It is a good idea to use an id to select these elements. During
- * code transformation it is likely that other template elements will be
- * inserted at the top of the body above yours, so something like
- * querySelector('template') is likely to break when built.
- * See http://dartbug.com/20911.
- *
- * Example:
- *
- *     <template id="my-template" is="auto-binding-dart">
- *       <div>Say something: <input value="{{value}}"></div>
- *       <div>You said: {{value}}</div>
- *       <button on-tap="{{buttonTap}}">Tap me!</button>
- *     </template>
- *     <script type="application/dart">
- *       import 'dart:html';
- *       import 'package:polymer/polymer.dart';
- *
- *       main() {
- *         var template = document.querySelector('#my-template');
- *         template.model = new MyModel();
- *       }
- *
- *       class MyModel {
- *         String value = 'something';
- *         buttonTap() => console.log('tap!');
- *       }
- *     </script>
