4405	MultiValueField does not allow sub-fields to be blank	adurdin@…	Konrad Beiske	"If even one of a MultiValueField's sub-fields is blank, a ValidationError is raised, even if that sub-field had `required=False`

In `django/newforms/fields.py`, line 530
{{{
            if self.required and field_value in EMPTY_VALUES:
                raise ValidationError(gettext(u'This field is required.'))
}}}

Line 530 should be changed to check the sub-field's `required` attribute:
{{{
            if field.required and field_value in EMPTY_VALUES:
}}}
