Of course as noted before, it is often a requirement that a user be  
able to override this setting via an interface in the web application  
itself. Ideally that wouldn't be required, but idealism isn't often  
achievable when web browsers are involved. :) The override may take  
the form of a cookie, data in a session, part of the url, or whatever  
else app specific. In the way I'd envision creating an application,  
processing the language pref inputs into the single "preferred  
languages order" attribute takes place in a resource near the top of  
the graph, for use by all resources under it in the application. Said  
resource has to communicate the information somehow.

I like CCE's description of his processing stages -- it seems to  
match the way I think as well, although he takes it to more of an  
extreme than I would.
