    <title>Introduction</title>
    <para>This is generated reference documentation for all
      user-specifiable processing instructions (PIs) in the DocBook
      XSL stylesheets for HTML output.
      <note>
        <para>You add these PIs at particular points in a document to
          cause specific &#8220;exceptions&#8221; to formatting/output behavior. To
          make global changes in formatting/output behavior across an
          entire document, it&#8217;s better to do it by setting an
          appropriate stylesheet parameter (if there is one).</para>

        well-formedness constraints (because the feature in XSLT
