		This test application demonstrates a number of features:
		<ul>
		<li>The ability to create and manipulate elements within an iframe.</li>
		<li>The ability to load a javascript file(s) inside an iframe</li>
		<li>The ability for iframes to have their own instance of xajax</li>
		<li>The ability for an iframe to communicate back to the parent</li>
		<li>The response command waitFor... which can wait for a custom condition to evaluate to true.</li>
		</ul>
		When you click the submit button, it will send a xajax request which in turn triggers the following:<br />
		The form values are displayed in the iframe and the main document.<br />
		The iframe is instructed to load a javascript file (iframe.js)<br />
		The main document frame waits until the javascript file is fully loaded (using waitFor)<br />
		The iframe.js invokes a xajax request (in the iframe to theFrame.php) which sleeps for 2 seconds, then returns 'iframe.js loaded'.<br />
		The iframe.js waits 4 seconds, then notifies the parent (main document) that the iframe.js file is fully loaded.<br />
		The main document displays that the iframe.js file is loaded in the iframe context.
		</div>
