        -
          - ':input[name="assistant_dean_email"]':
              value: '[current-user:mail]'
        - or
        -
          ':input[name="area_of_access"]':
            value: some_area
          ':input[name="current_logged_in_user"]':
            value: some_user

      {% if webform_token('[current-user:account-name]', webform_submission, [], options) == 'some_user' and
      data.area_of_access == 'some_access' %}TRUE{% endif %}
    '#whitespace': spaceless
    '#store': true
    '#ajax': true
