Comment (by Chouby):

 As far as I understood, the `lang` and `dir` attributes are global and can
 be applied to `a`. That's not for the linked document but for the label of
 the link.

 I wrote a [https://wordpress.org/plugins/polylang/ multilingual plugin]
 and would like to improve its accessibility. I am just starting in that
 domain so I have a lot to learn! In this plugin, I add the list of all
 languages in the admin bar and I use the native name. I understood that I
 should add the `lang` attribute for the language name beeing correctly
 pronounced.

 Here is a piece of html code that I found easily on internet:
 {{{
 <a lang="ar" hreflang="ar" title="arabe"
 href="//ar.wikipedia.org/wiki/">العربية</a>
 }}}
 For my own usage, I don't need the `hreflang` attribute because the menu
 does not switch the admin language but activates a language filter (for
 the list of posts for example). But it could make sense to add more
 attributes such as `hreflang` or `dir` to the white list for other usages.

 >This is only used for more than 2 words, because the switching of a voice
 will take some time and that's irritating for small pieces of text.
 I didn't know this rule, so in my case, that may be not useful. What do
 you think of the long list of available languages on all Wikipedia pages?
