> Because we now perform validation of processors mush more often (because we 
> want to know if a processor is invalid, even while it's running), we want to 
> know whether or not a validator's value can change due to the environment. If 
> not, then we know that the validity of a Processor hasn't changed since it 
> was started. However, if the validation can change due to environment, such 
> as a FileExistsValidator, we must validate the processor regardless of 
> whether or not the value has changed.
