Hi everyone, I’m happy to announce that I’ve created and released v1.0 of a Rendering Transformation to automatically number headings in a wiki page. It also contains a macro that can be used to reference a section by its id and this creates a link with the section number as the link label.
See http://extensions.xwiki.org/xwiki/bin/view/Extension/Numbered%20Reference%20Macro/
Enjoy!
