Not sure I fully understand your requirements, but maybe:
requires=IS_IN_SET(..., multiple=(0, MAX_SIZE_OF_SET))
The "multiple" arguments indicates multiple items can be selected, and it
can either be a boolean or a list/tuple specifying a minimum and maximum
number of values. In the latter case, the minimum can be 0, allowing an
empty set.
