| Does it mean that there is no constraint on parameters or outputs ?

You don't get to specify outputs when you call an atomic step, so they
aren't really relevant are they?

There are no constraints on paramters, beyond the fact that you can
only specify them on a step that has (at least one) parameter input
port.
