Hmmm... It _should_ apply to everything, but maybe it only 
applies to the outer-level declarations. Certainly, in most 
cases, I'd be surprised if marking everything in a module with 
those attributes would work on the first go. It's _possible_, 
depending on what you're doing, but in my experience, odds are 
that you're doing _something_ that violates one or all of those 
in several places.
