Hello,
I have evaluated the following function found in ox-html.el
and indeed the S5 html works when this function is defined.
(defun org-html-end-plain-list (type)
"Insert the end of the HTML list depending on TYPE."
(case type
(`ordered "</ol>")
(`unordered "</ul>")
(`descriptive "</dl>")))
I don't know if this function should appear accordly in
ox-S5.el or elsewhere. As I don't use development environment
I don't know how a patch has to be submitted.
Anyway thank for your help. Hope it can be useful for the
person who knows how to implement it and where.
Regards
