In this new variant, we have made four changes:

 * We've made it so you don't have to give the type of a list of
   name-value pairs (removed itemtype="").

 * We've made it so you can declare the relationship from the page to
   the list.

 * We've made it so that to name a list of name-value pairs, you just
   give it a name-value pair with the name "itemid", instead of using
   the item="" attribute.

 * We've renamed item="" to itemscope="" to show that it is declaring
   the scope of subsequent itemprop=""s.

So instead of:

   <div item="http://example.com/fruits/apple" itemtype="http://example.com/fruit">
    <div itemprop="tree" itemtype="http://example.com/tree" item>
     <span itemprop="country">USA</span>
    </div>
   </div>

You now have:

   <div itemprop="http://example.com/fruit" itemscope>
    <link itemprop="itemid" href="http://example.com/fruits/apple">
    <div itemprop="tree" itemscope>
     <span itemprop="country">USA</span>
    </div>
   </div>
