-<para>This is generated reference documentation for all
-      user-specifiable processing instructions (PIs) in the
-      “common” part of the DocBook XSL stylesheets.
-      <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>
