    <title>Introduction</title>

    <para>This is generated reference documentation for all
      user-specifiable processing instructions (PIs) in the DocBook
      XSL stylesheets for FO output.
      <note>
        <para>You add these PIs at particular points in a document to
          cause specific “exceptions” to formatting/output behavior. To
          make global changes in formatting/output behavior across an
          entire document, it’s better to do it by setting an
          appropriate stylesheet parameter (if there is one).</para>
