How can I find out whether an element has a declared content
of empty? I need this information in an SGML to SGML transformation using
jade -t sgml to choose between the "element" or "empty-element" flow object.



As a hack, I defined

(define (empty-element?  #!optional (nd (current-node)))
  (node-list-empty? (children nd)))

But this returns true if the element was not declared empty
but happens to be empty in the document.
