Re: new itemscope or not?

Maybe it is an option to use both, a literal and a resource, at the same 
time?

    <div itemscope itemtype ="http://schema.org/Book">
       <span itemprop="author" itemscope 
itemtype="http://schema.org/Person"><span itemprop="name">Shakespeare, 
William</span></span>
       <meta itemprop="author" content="Shakespeare, William" />
    </div>
