Don't know how many of your institutions render EAD on the fly via web browser, but you might be interested in this discussion: This thread within the "blink-dev" discussion for Chrome's new rendering engine ... examines the possibility of removing support for XSLT from the browser. If so, Blink would be the first major browser to remove support: (https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/KZ0eaL-3vQY) There is some discussion of usage on the web at large, but note Eric Seidel's (of the Chrome team) comment from 4/23: "My suspicion is that neither can be removed from the platform at this time. But both are probably good opportunities for later removal or replacement with JS-based polyfills. I expect removing the need to ship libxslt as part of Chrome to be a small (but non-trivial) binary size win." (https://groups.google.com/a/chromium.org/d/msg/blink-dev/KZ0eaL-3vQY/6Yh4qSidA6AJ)
