/**
* HTML attribute functions and filters. The purposes of this is to provide a way for theme/plugin devs
* to hook into the attributes for specific HTML elements and create new or modify existing attributes.
* This is sort of like `body_class()`, `post_class()`, and `comment_class()` on steroids. Plus, it
* handles attributes for many more elements. 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.
