      off, or a string containing the logfile in which log errors too.

   This function allows you to set the file in which you want XSLT log
   messages to, XSLT log messages are different than error messages, in
   that log messages are not actually error messages but rather messages
   related to the state of the XSLT processor. They are useful for
   debugging XSLT, when something goes wrong.
  </para>
  <para>
   By default logging is disabled, in order to enable logging you must
   first call <function>xslt_set_log</function> with a boolean parameter
   which enables logging, then if you want to set the log file to debug to,
   you must then pass it a string containing the filename.
