+// class has necessary mapping to other source info - for example, it calls
+// NotificationDelegate supplied by client when someone clicks on a Notificaiton
+// in MessageCenter. Likewise, if a Profile or Extension is being removed, the
+// map makes it possible to revoke the notifications from MessageCenter.
+// To keep that set, we use the private ProfileNotification class that stores
+// a superset of all information about a notification.
+
+// TODO(dimich): Consider merging all 4 types (Notification, QueuedNotification,
+// ProfileNotification and NotificaitonList::Notification) into a single class.

nit: There are still 4 more misspellings of Notification in the above
paragraphs.
