Also found in the __init__ of MultiValueField:
def __init__(self, fields=(), *args, **kwargs):
super(MultiValueField, self).__init__(*args, **kwargs)
# Set 'required' to False on the individual fields, because
the
# required validation will be handled by MultiValueField, not
by those
# individual fields.
for f in fields:
f.required = False
self.fields = fields
Why is a requirement to set to False all the individual fields?
