v1 is a validator, not a generator — building a sitemap requires crawling the whole site, which isn't feasible purely client-side. Need one generated and kept in sync automatically? That's exactly what ThrillSEO handles.

Valid structure ≠ indexed — Google may still choose not to crawl or index listed URLs. Cross-link: Hreflang Generator for xhtml:link alternates found in sitemaps. Everything above runs locally except an explicit URL fetch. Tool provided free by ThrillSEO.
