Workflow variables type User, Role and Substitution List

Does anyone know where I can find more specific documentation on using the List type variable for the above named? (V7.1)

If I create a Role type variable named "Supervisors" and check the List option, what entry type can I use to load that variable? (I'm assuming an Arithmetic Expression like "Supervisor One" AND "Supervisor Two" AND "Supervisor Three").

And if I use it in a condition what will that variable contain? For example in a Validation, WF_ASSIGNED_TO = GV_SUPERVISORS, does it check each and compare for each element?

Thanks,
