I need something like this for exporting org-mode to html (Jambunathan
and I are rewriting the export routines to cover export to odt too).

BTW, I came up with this for the moment:


;; (org-newhtml-escape-id "fig:5")
;; (org-newhtml-escape-id "56")
(defun org-newhtml-escape-id (id)
  "Return a valid id string.
See URL http://www.w3schools.com/tags/att_standard_id.asp";
  (setq id (replace-regexp-in-string "\\`\\([^A-Za-z]\\)" "ANON-\\1" id nil))
  (setq id (replace-regexp-in-string "[^A-Za-z0-9_.-]" "-" id t)))
