Is it semantically correct to include two <nav> elements on a page for primary AND secondary navigation?

Question

My page has two sections where there are a "list of links". The first is the primary i.e.

<nav>
    <ul>
        <li><a href="/">Homepage</a></li>
        <li><a href="/testimonies.html">Testimonies</a></li>
        <li><a href="/contact-us.html">Contact Us</a></li>
        ...
    </ul>
</nav>

This is a no brainer, ‘nav‘ is suitable here.

The second list of links is a list of categories such as:

Rock Music
Dubstep Music
Dance Music
Hip Hop Music
Electro Music
Classical Music
...

Is it semantically correct to use a element for the secondary list?

Answer 1

Depending on the documentation...seems legit. There is an example with two nav elements for primary and secondary navigation as well.
