 * When an {@code include} tag points to a layout with a {@code merge} top level item, there is no
 * top level item that can use the {@code include} item as cookie.
 * <p/>
 * This class is used as a cookie for all items under the {@code merge} (while referencing the
 * original {@code include} cookie) to make it easy on the client to group all merged items
 * into a single outline item.
