/**
* This is a stripped down version of Justin Tadlocks attributes and elements addition. I'll add the
* classes and divs "manually" and add Schema.org support via filters below.
*
* The biggest benefit of using this is to provide richer
* microdata while being forward compatible with the ever-changing Web. Currently, the default microdata
* vocabulary supported is Schema.org.
