Hyperlink tag is always the item to find to process the event on (Notify or go to depending on THAT item's flags). This could be the item itself or someone else. If the item is inserted with USERXAML, then the tag is specified by the user. If it's not custom XAML,then the Hyperlink tag is made from the FQN of the item (The 2nd argument to NavInsertItem);
For the target item
If MESSAGEBAR_NOTIFY flag, then Hyperlink tag is the object to notify e.g. "MESSAGEBAR\NotificationWarning". So basically the target and notify items are the same. This is an item that's been inserted with NavINsertItem.
If not MESSAGEBAR NOTIFY then target item's description is the nav location to go to
