2. hasDummyRoot is an alphanumeric data item or literal hosting a boolean value (e.g. "0", "1", "true", "false", "yes", "no", "on" or "off"). If the boolean value is TRUE, then the top level item of Record-Definition is discarded and will not appear in the JSON stream . This parameter can be NULL, in such case, FALSE is assumed.
