18128	Remove unsupported sequential link types	Elpie	nacin	"All sequential link types used in WordPress, with the exception of the link rel='prev' and link rel='next' that are output by adjacent_posts_rel_link_wp_head, are unsupported by any browser or assistive device. 

These were considered in the early drafts of the HTML5 spec but were officially removed last year. See: [http://lists.w3.org/Archives/Public/public-html/2010Nov/0042.html]

Now that the default theme shipping with WordPress is using HTML5 it makes sense to remove the unsupported link types. Leaving them in invalidates TwentyEleven and once the HTML testing tools are improved this will become obvious to users. 

Recommend removing the relevant functions from link-template.php and the actions from default-filters.php"	defect (bug)	closed	normal	3.3	Validation	3.2.1	normal	fixed	has-patch	Elpie sirzooro
