/**
 * Asynchronously update an element with response of an XMLHttpRequest-based emulation of a form submission. <p>The form <code>action</code> and 
 * <code>method</code> attributess will be followed. Passing a configured XSLT processor will result in 
 * transforming and updating the server response before using it to update the target element.
 * You can also pass a callback function to be executed when the update is finished. The function will be called as 
 * <code>functionName(oNode, oTargetElement);</code></p>
 * <p>Here is an example of using this in a form element:</p>
 * <pre name="code" class="xml">
 * &lt;div id="targetId"&gt; this content will be updated&lt;/div&gt;
 * &lt;form action="/my/form/handler" method="post" 
 *     onbeforesubmit="return Sarissa.updateContentFromForm(this, document.getElementById('targetId'));"&gt;<pre>
 * <p>If JavaScript is supported, the form will not be submitted. Instead, Sarissa will
 * scan the form and make an appropriate AJAX request, also adding a parameter 
 * to signal to the server that this is an AJAX call. The parameter is 
 * constructed as <code>Sarissa.REMOTE_CALL_FLAG = "=true"</code> so you can change the name in your webpage
 * simply by assigning another value to Sarissa.REMOTE_CALL_FLAG. If JavaScript is not supported
 * the form will be submitted normally.
 * @memberOf Sarissa
 * @param oForm the form submition to emulate
 * @param oTargetElement the element to update
 * @param xsltproc (optional) the transformer to use on the returned
 *                  content before updating the target element with it
 * @param callback (optional) a Function object to execute once the update is finished successfuly, called as <code>callback(oNode, oTargetElement)</code>. 
 *        In case an exception occurs during excecution and a callback function was provided, the exception is cought and the callback is called as 
 *        <code>callback(oForm, oTargetElement, exception)</code>
