Hi Nicolas,

I was thinking that this should yield a citation object with a structure like:

('citation ...
  :common-prefix pre
  :common-suffix post
  :references ((:prefix pre1
                :key "k1"
                :suffix post1 ...)
               (:prefix pre2
                :key "k2"
                :suffix post2 ...))
  ...)

Would that work?

Hmm, I don't quite understand what you mean.  This is not allowed by the
grammar (as far as I can tell), so that should not parse as a citation
object, IMO.

Oh, I did not realize there were outstanding issues with this.  I
remember Rasmus not liking `&'.  I'm fine with changing it, though I
cannot think of a better symbol.  Does someone think we should not have
a way of indicating that a reference should produce a full bibliography
entry?  Or that we should indicate it in some other way?  

Best,
Richard
