If the page doesn't have the right protection level --     it is put in a tracking category and the icon is not displayed --     (optional). -- Note: this is just a convenient place to store the data. The subtables are -- accessed from the code manually, so adding new subtables won't automatically -- add new icons, and removing subtables may break things. --
