Can I use tag for list of article tags?

Question

After the article I have list of tags related to article. Is it semantically correct to wrap list of those tags in <nav> html tag? If no, what would be the proper one?

<nav class="tags">
    Tags:
    <ul>
        <li><a href="#">Tag1</a></li>
        <li><a href="#">Tag2</a></li>
        <li><a href="#">Tag3</a></li>
    </ul>
</nav>

MDN states:

1. Not all links of a document must be in a <nav> element, which is intended only for major block of navigation links; typically the <footer> element often has a list of links that don't need to be in a <nav> element.
2. User agents, such as screen readers targeting disabled users, can use this element to determine whether to omit the initial rendering of this content.

Answer 1

The <nav> tag defines a set of navigation links.

Notice that NOT all links of a document should be inside a <nav> element. The <nav> element is intended only for major block of navigation links.

Browsers, such as screen readers for disabled users, can use this element to determine whether to omit the initial rendering of this content.

Answer 2

The tags are part of the article’s metadata (just like the author name, the publication date, etc.), so they should be in a footer element, and this footer should be inside the article element:

<article>
  <footer><!-- tags --></footer>
</article>

(Some might use header instead of footer, but its default role banner is not really appropriate, and it can’t have the contentinfo role, which would be appropriate.)

For such a simple list of tags, another sectioning element isn’t really needed.
