+/**
+ * The `auto-binding` element extends the template element. It provides a quick
+ * and easy way to do data binding without the need to setup a model.
+ * The `auto-binding` element itself serves as the model and controller for the
+ * elements it contains. Both data and event handlers can be bound.
+ *
+ * The `auto-binding` 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.
+ *
+ * Example:
+ *
+ * <template is="auto-binding">
+ * <div>Say something: <input value="{{value}}"></div>
+ * <div>You said: {{value}}</div>
+ * <button on-tap="{{buttonTap}}">Tap me!</button>
+ * </template>
+ * <script>
+ * var template = document.querySelector('template');
+ * template.value = 'something';
+ * template.buttonTap = function() {
+ * console.log('tap!');
+ * };
+ * </script>
+ *
+ * @module Polymer
+ * @status stable
