Yes.

For example a car. Car must have some basic functionality, that is mandatory. 
Now, if you want to do some additional stuff with your car, you need to require 
that and when you require that it becomes mandatory.

It's mandatory, that car moves on the road. If you need to carry bigger load, 
then you require the car to be a bit different. Still a car, but with mandatory 
functions that you need for your job, like a big booth or something.

If you don't require a functionality it is not mandatory.
