Hello, newbie inbound

 Hello everyone:

I'm trying to create Slides with Docbook, I even bought the O'reilly book!

I use Debian, and installed the package docbook-slides, but when I try 
to create a PDF with : 

/sgmltools -bpdf slides.sgml/


Of a SGML Like this One:

*/<?xml version='1.0'?>
<!DOCTYPE slides PUBLIC "-//Norman Walsh//DTD Slides XML V3.0b1//EN"
                
"http://docbook.sourceforge.net/release/slides/3.0b1/slides.dtd";>

</slidesinfo>
<foil><title>Foil Title</title>

</foil>
</slides>/*


I get those errors, I will only paste 10, but there are many more:

.....

Is anyone able to help me? I want to convince teachers in my university 
to use docbook, I didn't have such problems with docbook when creating 
Book, and articles

Thanks a lot for your help.
