//! Pure-function sitemap XML serialisation: turns slices of [`SitemapUrl`]
//! into the `urlset` and `sitemapindex` documents required by the sitemaps.org
//! 0.9 protocol. The `xhtml:link` namespace is declared on every `<urlset>`
//! so per-URL `<xhtml:link rel="alternate" hreflang="…">` entries validate
//! against Google's hreflang spec.
