* Links

  How many links like that will exist?
  Only links from external sites will break.
  I found one section link, but that's "sec-1"  (on de.wikipedia.org)

  Most links to certain sections use those custom IDs I guess.

* org-info.js

  I would then add the underscore to the regexp in org-info.js.
  People who use that will have to upgrade, too.

* Are there more modules involved??

sh$ grep -Fr sec- .
 org-docbook.el:(defcustom org-export-docbook-section-id-prefix "sec-"
 org-exp.el:			(format "sec-%s" (org-section-number level))))
 org-html.el:				(setq href (format "sec-%s" snumber))
 org-html.el:	(setq href (cdr (assoc (concat "sec-" snumber) org-export-preferred-target-alist)))
 org-html.el:	(setq href (or href (concat "sec-" snumber)))
 org-latex.el:		  (sec-depth (length org-export-latex-sectioning)))
 org-latex.el:	      (if (> hl-levels sec-depth) sec-depth hl-levels))))

Let's do it.

You don't want people to point on orgmode saying "They don't even use
valid CSS-IDs", do you?

And I guess most of us users will just be fine with it.

      Sebastian
