When All has been selected, all items in the age-based and in the
contents-based lists are locked. If, while All is selected, any other item, either an
age-based or content-based item, is unselected, then All is automatically
unselected.
None is the selection for items that either have no rating information or have a
rating of None. Both will be locked. When an item on the age-based list is
selected, all items below that item of the same group are locked as well. When
you select a content-based rating, all identical content- based ratings in the
younger age-based categories are also selected.
