+/*
+``<iron-form>` is an HTML `<form>` element that can validate and submit any custom
+elements that implement `Polymer.IronFormElementBehavior`, as well as any
+native HTML elements.
+
+It supports both `get` and `post` methods, and uses an `iron-ajax` element to
+submit the form data to the action URL.
+
+  Example:
+
+    <form is="iron-form" id="form" method="post" action="/form/handler">
+      <paper-input name="name" label="name"></paper-input>
+      <input name="address">
+      ...
+    </form>
+
+By default, a native `<button>` element will submit this form. However, if you
+want to submit it from a custom element's click handler, you need to explicitly
+call the form's `submit` method.
+
+  Example:
+
+    <paper-button raised onclick="submitForm()">Submit</paper-button>
+
+    function submitForm() {
+      document.getElementById('form').submit();
+    }
