Hi, The <html>, <head> and <body> tag has been optional since HTML4 (http://www.w3.org/TR/html4/struct/global.html) and I was wondering if it is still the case with HTML5 since it no longer specify that the tags are optional on the current HTML5 spec page (http://www.w3.org/TR/html5/semantics.html#the-html-element).
