20  * Implementation of {@link com.sslexplorer.ajax.AbstractAjaxXMLAction}
21  * that returns an XML document containing a list of roles.
22  * <p>
23  * Two request parameters are supported. First, the optional <b>role</b>
24  * which may contain a search string and secondly <b>maxRows</b> which is
25  * an integer, defaults to 10 and determines the maximum number of results to
26  * return. If <b>account</b> is not supplied, all roles (up to the
27  * specified maximum rows) will be returned.
