 Currently, the `body_class` only allows for filtering with additional
 classes. For users that want to add other items, they have to manually
 edit the theme files. The best example of this is schema.org body elements
 (itemtype and itemprop).

 The diff file shows two things:

 1. the new `body_items` function that grabs any items added via filter, if
 they exist.

 2. the modified `body_class` function, which appends the output with the
 items if they exist.

 The patch, as I've written it, allows for this additional filter to be
 included without interfering with how themes / plugins interact with the
 current `body_class` filter, and doesn't require theme authors to include
 an additional tag in their themes.

 Below is an example function that could be placed in a theme or plugin to
 add other items to the body tag element.


 {{{
 function schema_bodyitems($item) {

         if (is_page() ) :
                 $item[] = 'item-foo="item-bar"';
         endif;

         $item[] = 'itemtype="http://schema.org/Blog"';
         $item[] = 'itemscope=""';

 return $item;
 }

 add_filter('body_items','schema_bodyitems');
 }}}
