Removing XSLT from Chromium

Mason Freed and Dominik Rottsches have published a documentwith a timeline and plans for removing Extensible Stylesheet LanguageTransformations (XSLT) from the Chromium project and Chromebrowser:

Chromium has officially deprecated XSLT, including the XSLTProcessorJavaScript API and the XML stylesheet processing instruction. Weintend to remove support from version 155 (November 17, 2026). TheFirefox and WebKit projects have also indicated plans to remove XSLTfrom their browser engines. This document provides some history andcontext, explains how we are removing XSLT to make Chrome safer, andprovides a path for migrating before these features are removed fromthe browser.

LWN covered the WebHypertext Application Technology Working Group (WHATWG) discussionabout XSLT in August.
