Navigation Paths can have aliases that are immutable references to navigation paths. By . By using aliases the underlying navigation path can change and the framework will still be able to find it via its alias. NavInsertItem allows you to specify an alias when you add the item and by convention aliases are names surrounded by { } characters. Use the NavItemHelpers function MakeAliasForName to easily create an alias from a name.

If you have a component that needs to allow others to place nodes beneath it know about its navigation items (To place tree node under it for instance) then publish the alias not the full navigation path. So long as you don't rename the alias then you can move/rename the navigation path within the hierarchy and client code will continue to find your item via its alias.
