XHTML/CSS query

[j4]

Okay, this may be a dumb question, but is there a way in XHTML/CSS to create a nested ordered list like this:

1. a list with some stuff in:
        1.1 stuff here
        1.2 more stuff
        1.3 guess what, a nested list:
                1.3.1 stoat
                1.3.2 weasel
                1.3.3 badger
        1.4 no list here

2. another list, or whatever

etc.?

I have looked in all the usual places and they all seem to say "no, can't be done", but you guys are clever...

Update: I really do mean with the numbering as above (1, 1.1, 1.1.1 etc.) not just nested lists in general -- sorry for not being more clear. And it looks like the answer's "no" anyway. :-/
