Hi,
    I try to define a new export backend in the new export framework. My
export backend should behaves like the html except that it transcodes
*bold* differently.  I try to following the Worg tutorial
http://orgmode.org/worg/dev/org-export-reference.html , ox-html.el and use
org-export-define-derived-backend. I can see the new backend showing up in
the export menu(C-c C-e), but my transcoder for bold is not used.  Any help
or reference pointer is appreciated.

(org-export-define-derived-backend 'my-html-enlish 'html
  :traslate-alist '((bold . my-org-html-english-bold))
   :menu-entry
  '(?E "Export to HTML-ENGLISH"
       ((?H "As HTML buffer" my-org-html-english-export-as-html)
)))
------------------------------
(defun my-org-html-english-export-as-html
  (&optional async subtreep visible-only body-only ext-plist)
 "This is almost copied from org-html-export-as-html except using my newly
defined backend"
  (interactive)
  (org-export-to-buffer 'my-html-enlish "*Org HTML-ENG Export*"
    async subtreep visible-only body-only ext-plist
    (lambda () (set-auto-mode t))))
