  <info>
    <p>
      This test checks external-graphics and the handling of linebreaks.
      It is unclear at the moment if consecutive images without intervening white space
      actually should have a linebreak opportunity between them or not. Fop currently
      takes the "there is no break opportunity" view and the checks test accordingly.
