    <para>
      The xmllint program parses one or more XML files, specified on the
      command line as <replaceable>xmlfile</replaceable>. It prints various
      types of output, depending upon the options selected. It is useful for
      detecting errors both in <acronym>XML</acronym> code and in the
      <acronym>XML</acronym> parser itself.
