Valid fields not showing up

function mymodule_views_data() {
...
  $data['mymodule']['myfield'] => array(
    'title' => t('My module field'),
    'help' => t('Help text'),
    'field' => array(),
  );
..
  return $data;
}

The field "My module field" will not show up because of too restrictive validation checking. As it is sufficient to define title, group or help outside the field array the $info[$key] variable should be allowed to be empty.
