Hi Nicolas,

With this change, what's the proper way to get the citation-references
inside a citation?  Before this change, one could simply do:

(org-element-property :references citation) 

to get the references in a citation; what's the equivalent incantation
now?

Your example here makes it look like I should be able to do something
like:

#+BEGIN_SRC elisp
(let* ((citation (org-element-context))
       (references
          (remove-if-not
	   (lambda (o) (and (listp o) (eq (car o) 'citation-reference)))
	   citation)))
   ; ...
   )
#+END_SRC

But, AFAICT, citation objects do not actually have citation-reference
objects within them, at least when returned by org-element-context.

I'm sure there is something simple I am misunderstanding here about how
nested objects work...can you enlighten me?  

Thanks!

Best,
Richard
