 *
 * @param[in] method  A config_eap_method structure that contains all of the
 *                    variables that we want to convert to XML.
 * @param[in] write_all   If set to TRUE, we will write all of the configuration
 *                        options to the XML node tree, no matter if their values
 *                        are set to the default or not.
 *
 * \retval NULL on error
 * \retval xmlNodePtr containing the <EAP> tree in a format that is used by 
 *         libxml2.
