[docbook-apps] Detecting last page

[DeanNelson]

All,
 
I need to detect the last page (not back page) in my article style sheets  
so I can put a legalnotice at the bottom of the last page. Any ideas?  (FOP  
1.0, DB 4.5)
 
It appears that pageclass does everything except "last page".
 
Regards,
Dean Nelson
