<urlset ...>`
    No, that's messy.
    I'll just do:
    ``
    `<urlset ...>`
    ...
    `</urlset>`
    ``
    ``

    One last check on the `div` thing. If I put a `div` around an XML `urlset`, it's 100% invalid XML. The prompt says "THIS IS A STRICT XML SITEMAP". I will prioritize the XML validity.

    Wait, the prompt says: "All dynamic text (titles) inside tags MUST be wrapped in `htmlspecialchars(..., ENT_XML1, 'UTF-8')`."
    I will check if I missed any other titles.
