Index, first and last meta links and rel attributes

Question

Are the obsolete links "index", "first" and "last" meta and rel attributes?

I am developing cms that uses them for pagination in chapter meta-links and rel-attributes in the navigation folder.

But when I wanted to check the page as html5, I got them as a bad value.

Where did they go? only "prev" and "next" pass the test.

Even on the whatwg list, they do not exist http://www.whatwg.org/specs/web-apps/current-work/multipage/links.html#linkTypes

Should I delete them?

Thanks.

HTML5 accepted this Change Proposal as described here

Honestly, the arguments are dubious. There are plugins for browsers, one of which I use that use rel = "first" and rel = "last".

The rel registry is now officially launched by Microformats.com . We hope that over time the “index”, “first” and “last” relay types will be read here.
