arbiterName

The discipline by name, so a scenario or an app can change it without holding an arbiter.

Only the two priority disciplines have names. An alternating or bounded-batch arbiter takes the times and counts that are its discipline -- a batch of two with a five-minute cap is a different policy from a batch of ten with a one-minute cap, not the same policy tuned differently -- so naming one would mean choosing those numbers on the modeller's behalf and hiding the choice inside a string. Assign the arbiter to use those, and read this property to see what is in force: it reports the arbiter's own toString when no name stands for it.
