I like that too.  I was thinking something along the same lines when I 
read the earlier posts in this thread, though (as you mentioned) I would 
have used the for attribute as an IDREF instead.

I can, however, think of the following issues:
1. Can it only refer to a <li id="foo"> element?  Are there any
    use-cases for allowing it to refer to other elements?

2. What about <li>s in <ul> or non-<li> elements?  What value would be
    used, or should it just use the fallback content?

3. Assuming <ref> gets replaced with the value of the counter from the
    target element, what happens if the counter has been removed with CSS
    i.e. what's the default value?  Should it just use the fallback
    content provided in such cases?

4. Authors are likely to provide fallback content that is dependant upon
    the presentation.  i.e. Your example used "f", but assuming no
    type="a" attribute and no CSS, the list item's counter will probably
    display "6." instead.
    It's probably not a serious issue, since users may be smart enough to
    work out that "f" is the 6th letter, and thus refers to the 6th item.
