     Note that it is not just a new value. The new value could be an expression
     containing other parameters. Not only is the overridden parameter no longer
     dependent on any parameters in its old definition, but it is now dependent on
     any parameters in its new definition, if they change values. The old
     definition has been completely replaced with the new one.
     
     I'm not sure that the word "force" is a good choice here either, given the
     existence of force statements, which are unrelated to this.
