Ohh sry again ahah, I was speaking about the xmlns:xhtml name space, needed when u use alternate link like languages etc.. :

// example
url: "myurl.com",
alternates: {
  en: "myurl.com/en"
}

This add the namespace for xmlns:xhtml but its rendered weirdly in chrome

I couldn't find information about sitemaps requiring xmlns:xhtml attribute, can you provide link to it?

found it

it is being used here: https://developers.google.com/search/docs/crawling-indexing/sitemaps/combine-sitemap-extensions

U can test creating a sitemap with sitemap.ts with alternates

yup
