Hm... I'd prefer not having to hardcode things in the document.  Here
is a little attempt that gives strange results:


  (define (last-descendant-node nd)
    (if (node-list-empty? (children nd))
  	nd
  	(last-descendant-node (node-list-last (children nd)))))      
  
And then I insert the following to get my number of pages:

  (element-page-number-sosofo (last-descendant-node (sgml-root-element)))


Then I end up ROTFL when the formatted postscript reads "Page 1 of n"
and so on. :)

Did I miss something ? (appart from the potential possibility of
getting a wrong number if the last-descendant-node computed spans
several pages, that is)
