[xwiki-devs] [New Rendering] How to implement section editing/Interface Extension status

Hi, In the new rendering implementation I need to implement section editing. So far it was done in XWikiHeadingFilter (ie. in the rendering). However I don't believe it should be done in the rendering module since this is something that depends on the skin used. I think the rendering should generate a placeholder only and it's up to the skin or templates to replace this placeholder by an image+link to edit a section. Thus I'm asking how we could do this? I think this is what Interface extensions are about, am I right? Sergiu any idea? Anyone? Thanks -Vincent
