>&#13;     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.

>&#13;     By default logging is disabled, in order to enable logging you must 
     first call <B
CLASS="function"
>xslt_set_log()</B
> 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.
