You could do it that way, but it's not quite what I was envisioning.

I was imagining that the ::footnote pseudo-element would simply *not 
exist* if no element uses the 'footnote' counter in its content 
property. Kind of like the ::first-line pseudo-element would (I imagine) 
not exist for an element that, for whatever reason, contained no line 
boxes (a replaced element, say).

The difference becomes apparent if I try to do something like:

fn::footnote { content: 'Hello, I'm a footnote' }

*without* specifying content: footnote for any of the actual fn 
elements. With your interpretation, I'd still get a footnote for every 
fn element but no way to get to them from the actual 'fn' elements. With 
mine, the fn::footnote selector wouldn't match anything. Essentially, 
the difference between our interpretation is whether this combination:

fn::footnote { content: 'A footnote' }
fn[note] { content: footnote }

<fn/><fn/><fn note="true"/><fn/><fn/>

gives one footnote or five.

There's worse already in CSS...
