If you're only using the schema to validate that your code produces a valid 
manifest file (based on the user's input to your gui) that's still useful 
(IMHO).  You don't have to put it in your application's logic to validate 
every file since the creation of the manifest file is under your 
control...but if you do have it there, you might look at it like having 
test/debug code to catch errors early on.
