For each variant link, for example: <a href="/zh-tw/Wikipedia:%E4%BA%92%E5%8A%A9%E5%AE%A2%E6%A0%88/%E6%B6%88%E6%81%AF" >台灣正體</a> add a <link> element to the <head> section of the document, thus: <link href="/zh-tw/A" lang="zh-tw" hreflang="zh-tw" rel="alternate" title="台灣正體"> Bug 24742 is similar, but does not cover link headers.
Already implemented in r74827
Is 74827 the correct number? I can't see anything about rel-alternate there.
r75617 is the correct rev
I was actually thinking of what's requested in Bug 4901 - "lang and hreflang attributes for interwiki links", to which I've added a request for rel="alternate"
