TIL XSLT support ends November 2026

Chromium has officially deprecated XSLT, including the XSLTProcessor JavaScript API and the XSLT processing instruction. We intend to remove support from version 158 (November 17, 2026). The Firefox and WebKit projects have also indicated plans to remove XSLT from their browser engines.
