[xwiki-users] Patch to templates/docextra.vm : where to report in jira ?

Dear XWiki Users, I have a little patch for the "docextra.vm" template which I would like to submit to the issue tracker, but I am not sure where to post it. The file to patch is in the SVN repository at http://svn.xwiki.org/svnroot/xwiki/platform/web/trunk Which category / project in jira does this part belong to? Is this still "XWiki Core" aka XWIKI or is it one of the skins, e.g. "XWiki Toucan Skin" aka XSTOUCAN ? Cheers, Clemens
