/**
 * The xajaxResponse class is used to create responses to be sent back to your
 * Web page.  A response contains one or more command messages for updating
 * your page.
 * Currently xajax supports 21 kinds of command messages, including some common
 * ones such as:
 * <ul>
 * <li>Assign - sets the specified attribute of an element in your page</li>
 * <li>Append - appends data to the end of the specified attribute of an
 * element in your page</li>
 * <li>Prepend - prepends data to the beginning of the specified attribute of
 * an element in your page</li>
 * <li>Replace - searches for and replaces data in the specified attribute of
 * an element in your page</li>
 * <li>Script - runs the supplied JavaScript code</li>
 * <li>Alert - shows an alert box with the supplied message text</li>
 * </ul>
 *
 * <i>Note:</i> elements are identified by their HTML id, so if you don't see
 * your browser HTML display changing from the request, make sure you're using
 * the right id names in your response.
