Does that library use the browser's xslt?

I'm curious as to the scope of the problem, if html spec drops xslt, what the solutions would be; I've never really used xslt (once maybe, 20 years ago). In addition to just pre-rendering your webpage server-side, I assume another possible solution is some javascript library that does the transformations, if it needed to be client-side?

Found a js-only library, so someone has done this before: https://www.npmjs.com/package/xslt-processor
