# Pull Request Template
## Description
The Help Center sitemap endpoint (`/hc/:portal_slug/sitemap.xml`)
previously rendered a `<sitemapindex>` element while embedding article
URLs directly, which does not align with the sitemap specification.
This change fixes the structure by:
- Replacing `<sitemapindex>` with `<urlset>`
- Adding the required sitemap XML namespace
- Rendering each published article as a `<url>` entry with `<loc>` and
`<lastmod>`
This ensures the endpoint outputs a valid, self-contained sitemap
document.
Fixes#13334
