I'm struggling to understand the reasons for <hgroup>: wouldn't one or more h1..h6 elements wrapped in the same <header> imply just such a grouping without the need for such an element?
To illustrate my query, what is the difference between <header> <h1>HTML 5</h1> <h2>a new era of loveliness</h2> <nav> ... </nav> </header> and <header> <hgroup> <h1>HTML 5</h1> <h2>a new era of loveliness</h2> </hgroup> <nav> ... </nav> </header> ? -- Bruce Lawson Web Evangelist www.opera.com (work) www.brucelawson.co.uk (personal)
