(define (declared-empty gi)
  (equal? 'empty 
     (node-property 'content-type
        (node-list-filter 
           (lambda (nd) (equal? gi (node-property 'gi nd))) 
           (q-class 'element-type (grove-root))))))
 
But class element-type and its properties are prlabs1, thus the
information is not provided by (Open)Jade <= 1.2.2. The latest version
of Kathleen Marzalek's mif backend patches expand jades grove plan
to include prlabs1. We will try to integrate that in a future
OpenJade release.
