This is because `$query` defaults to * `$tag=`, and for this to work a new query var has to be added. * * @since 2.1.0 * * @global WP_Rewrite $wp_rewrite WordPress rewrite component. * @global WP $wp Current WordPress environment instance. * * @param string $tag Name of the new rewrite tag. * @param string $regex Regular expression to substitute the tag for in rewrite rules. * @param string $query Optional. String to append to the rewritten query. Must end in '='. Default empty. */
