If you are using the AddThis bookmarking plugin ( http://wordpress.org/extend/plugins/addthis/ ) then you need this plugin to make sure that the generated HTML by the AddThis plugin is Valid. The plugin adds the xmlns:addthis="http://www.addthis.com/help/api-spec" entry to the html head tag so that the custom attributes of the AddThis plugin are recognized properly.
