//CC 7/31/2018 client side validation using html5 is not suported by webform for fileupload so I wrote my own validation. 
jQuery( document ).ready(function() {
  jQuery('.js-form-file').attr('required', 'required');
  jQuery('.js-form-file').attr('aria-required', 'true');
  jQuery('.js-form-file').addClass('required');
});
