				string $custom_url:	Optional href for area.

				string $class		If your function is a method, set the class field with your class's name and SMF will create a new instance for it.
				bool $enabled:		Should area be shown?
				string $sc:			Session check validation to do on save - note without this save will get unset - if set.

				bool $password:		Whether to require the user's password in order to save the data in the area.
				array $subsections:	Array of subsections, in order of appearance.
