[docbook] Table of Contents Not Indented?

[Mike Potter <mikep at axentra dot com>]

Hi all:
 I'm very new to docbook, but very impressed so far.
 Over the last 2 weeks, I've got a bunch of XML files creating the 
documentation for our product, in both HTML and PDF format.  The only 
problem that I can't seem to solve is to get the table of contents 
indented in the PDF formatted version.   It looks like this:
1.  Intro
1.1 Next
1.2 Following
..
and I think it should look like this:
1.  Intro
     1.1 Next
     1.2 Following
...
If someone can tell me how to get this done, I'd really appreciate it.  
I think I'm missing something obvious, but I can't get it working.  I've 
checked all over the http://www.sagehill.net/docbookxsl site (this is 
the best resource I've found) as well as reading through some of the 
messages to this list, and the obvious Google searching.

I'm running RH Linux to compile the XML document.  I've used both the 
xsltproc command as well as the Saxon Java processor and both give me 
the same result.  The commands I've used are:
java com.icl.saxon.StyleSheet -o documentation.fo resolved.xml 
/usr/share/sgml/docbook/xsl-stylesheets/fo/docbook.xsl 
toc.indent.width=20 passivetex.extensions=1 admon.graphics=1 
use.extensions=0 section.autolabel=1 
section.label.includes.component.label=1 generate.section.toc.level=0
and
xsltproc --xinclude -output documentation.fo --stringparam 
toc.indent.width 20 --stringparam passivetex.extensions 1 --stringparm 
admon.graphics 1 --stringparam use.extensions 0 --stringparam 
section.autolabel 1 --stringparam section.label.includes.component.label 
1 --stringparam generate.section.toc.level 0 custom_fo.xsl documentation.xml

Thanks for your help.
