Oh, no no no :)  I mean "in order to pass contextual information from 
the client to the server, it must be settable on the client" (this is an 
obvious tautology).  I don't mean you *have* to set this information.  
When I say that interceptors are "mandatory" I mean "any serious library 
that plays in the middleware arena should provide some form of this 
functionality".  Not that you *have* to use them, or that you are even 
aware of them.  Of course I don't want to force everybody to pass extra 
information or use interceptors or anything! :)  None of my patches have 
required you to do anything extra or even be aware of the extra
