[xsl] Nested List

[siarom egrub <egrubs@xxxxxxxxx>]

Hi all,

I am trying to get a nested list to display correctly.
I came up with two different ideas, however, neither
work correctly. The snippet for the simpler idea is
below with explanations. In the other idea I was using
for-each loops in the ordered list template.

Could someone please tell me what I am doing wrong
here?

Thanks in advance for your help!!

Regards,
S. Egrub
