Hi Jerome, friends, The aside is actually only for the comments, attachments, history and info sections of the sidebar only. The reason behind this is that according to html5 specs: that is tangentially related to the content around the asideelement, and which could be considered separate from that content. Such sections are often represented as sidebars in printed typography. ( http://html5doctor.com/understanding-aside/) which I thought is appropriate for those sections. <section> The reason I used article as an overall wrapper for the "main content" (the stuff with the white background), according to the html5 specs: self-contained composition in a document, page, application, or site and that is intended to be independently distributable or reusable, e.g. in syndication. This could be a forum post, a magazine or newspaper article, a blog entry, a user-submitted comment, an interactive widget or gadget, or any other independent item of content." ( http://html5doctor.com/the-article-element/) I thought this is appropriate since the entire "main content" is the self contained part of the page that can be independent of the other parts (like menu, asides, sidebars etc.) The use of section I thought is appropriate because each gadgets is in a way a section/part of the overall article, and of the sidebar. section" (http://html5doctor.com/the-section-element/) These are just my thoughts on the components of a webpage of xwiki, however. Do you think this is not the correct interpretation of the xwiki parts? Thanks for looking into the code! Jonathan Solichin
