Facebook announced yesterday support for the open graph protocol [1]. It allows website to integrate themselves into the facebook social graph. They already have several partners that are going to deploy that with them. Their system is based on RDFa, and thus using xmlns attributes: [[ <html xmlns:og="http://opengraphprotocol.org/schema/" xmlns:fb="http://developers.facebook.com/schema/"> <head> <title>The Rock (1996)</title> <meta property="og:title" content="The Rock" /> <meta property="og:type" content="movie" /> <meta property="og:url" content="http://www.imdb.com/title/tt0117500/ "/> <meta property="og:image" content="http://ia.media-imdb.com/rock.jpg" /> ]] They're using XHTML 1.0 with the media type text/html. I don't think they're going to switch to application/xhtml+xml soon. Effectively, from a technical perspective, it's a great news for the RDFa community. But, from the point of HTML, Facebook and their partners are deploying xmlns attributes in HTML all over the Web, independently of what the HTML5 specification is currently saying. So, that makes me wonder how relevant the HTML5 resolution on ISSUE-41 is going to be, Philippe [1] http://developers.facebook.com/docs/opengraph
