In this mode boolean, null and integer types are preserved when possible.
String values "true", "on" and "yes"
are converted to TRUE. "false", "off", "no"
and "none" are considered FALSE. "null" is converted to NULL
in typed mode. Also, all numeric strings are converted to integer type if it is possible.
