<orderedlist>inheritnum and CSS problems

Hi,

I have attached Sample.xml that contains a nested orderedlist with
inheritnum = 'inherit'.  I have also attached my .css file that I
according to my interpretation of section 12.5 of the TR-REC for CSS,
should yield number like this:

1
2
  2.1
  2.2

But instead it yields:
1
2
  1
  2

Is  my browser (Mozilla) faulty or am I doing something wrong.
According to Bob's posting to docbook-apps in 11/2003, if my browser is
faulty, I need to modify a template.  Unfortunately my <xsl> knowledge
isn't up to that yet, would anyone have an example.

Thanks.

John

Yes, I do have some customizations, but none of them should (famous last
words) affect this.
