I guess the point is that XSLT 2.0+ is not shipped as part of browsers, nor is it expected to be in the future, considering the only implementation is (commercially licensed) Saxon, by the author of W3C's XSLT spec himself ;)

I can only hope this isn't the case, XSLT is a brilliant idea that's very underrated and a great tool to have in your toolbox.

I don't count how many times I've seen people attempting to create simple reports from some XML taken from some obscure back office and try to reinvent the wheel by doing some JSON conversion and process that from some other program that build up an html report
