 value itself may be invalid. Normally this will add an error to the model such as
-'restriction :before value was invalid'. These can be annoying if you are using 
+'restriction :before value was invalid'. These can be annoying if you are using
 procs or methods as restrictions and don't care if they don't evaluate properly
 and you want the validation to complete. In these situations you turn them off.
