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)
