Ah, I did overlook something. It’ll suffice, just need to let my users know it’s there.

Basically change:

<ul class="language">
  <li class='lang-item lang-item-4 current-lang'>
    <a hreflang='en' href='/en/'>English</a>
  </li>
  <li class='lang-item lang-item-5'>
    <a hreflang='da' href='/da/'>Dansk</a>
  </li>
  <li class='lang-item lang-item-3'>
    <a hreflang='sv' href='/sv/'>Svenska</a>
  </li>
</ul>

To:

<ul class="language">
  <li class="active">
    <a title="English" hreflang="en" class="en" href="/en/">English</a>
  </li>
  <li >
    <a title="Dansk" hreflang="da" class="da" href="/da/">Dansk</a>
  </li>
  <li >
    <a title="Svenska" hreflang="sv" class="sv" href="/sv/">Svenska</a>
  </li>
</ul>

In other words:
– Replace single quotes with double quotes.
– Apply class changes to <li> elements.
– Apply class changes to <a> elements.
– Add title attribute to <a> elements.

I don’t know how much work there is in creating the possibility for a custom walker to be registered, but personally I’d be happy with just an array list of elements and their respective data, such as ISO-639-1 language code, translated language name and whether or not it is the current language (and I think this would also be faster to implement).
