This is documentation about a configuration directive, which can be placed within Movable Type’s core configuration file, mt-config.cgi, to customize the behavior of the system.

This is a switch for whether the extra archive fields are enabled in MT. These fields are deprecated; but this setting is turned on in the mt_config table if the upgrade process can’t reliably deprecate the fields. An example of this would be an existing weblog that uses two separate domains for site url and archive url, or where the archive url is not a subpath of the site url.
