 * \brief Take the variables that are part of the config_trusted_server structure, and
 *        convert them to be a tree of XML nodes that libxml2 can work with.
 *
 * @param[in] cts  A config_trusted_server 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 <Trusted_Server> tree in a format that is used by 
 *         libxml2.
