The final example of the DnD statt sheet makes me think whether it's legal to nest <dl>s?

I.e. can we do

    <dl>
      <dt>Actions</dt>
      <dd><dl>...</dl></dd>
    </dl>

Yes. Any flow content is permitted inside a <dd>. See:

Plus, when curious about formal syntactic correctness, there is the validator.w3.org [1].

I do it to render nested JSON objects, for example.
