-The template looks very similar to a normal HTML page. The main difference is that the template contains a few <tt>&lt;com:&gt;</tt> tags. Each <tt>&lt;com:&gt;</tt> tag refers to a <a href="http://www.pradosoft.com/demos/quickstart/?page=Fundamentals.Controls">control</a> whose properties are being initialized with name-value pairs in the tag.

 A further enhancement to this page is to show some confirmation message on the page after the user submits feedback. And possibly, the browser may be redirected to another page if the submission is successful. We will leave these tasks to our readers.
