title: Sitecore HTML5 support
body: <p>I am having issues getting Sitecore 6.6 to support HTML 5 layouts and rich text content. I have followed the instructions <a href="http://apaceweb.com/blog/2011/09/05/make-sitecore-rich-text-editor-html-5-ready/" rel="nofollow">here</a>, but I still receive validation errors in the admin tools. Has anyone had any luck using HTML 5 with Sitecore? Does anyone know if Sitecore 7 supports HTML 5? Thank you!</p>
