The second lives in XML files and templates that nobody has opened in years, and it fails in a way that no automated check will report.

An XML document with an XSLT stylesheet reference is transformed by the browser at load time. The server sends XML. Chrome fetches the stylesheet, applies it, and shows the result. That is why some sites ship a feed or sitemap that looks like a styled page in a browser.
