That would really be a surprising turn of events, and what a turn it would be! Imagine if the next generation of browsers supported XSLT 3.0—entire cabinets full of blog engines, static page generators, and much more could be rewritten. I support this. XSLT is one of those technologies that is too good to disappear. On the contrary, while some JavaScript frameworks have already turned to dust, I can still rely on my XML toolchains to work in 40 years' time.
As long as you only use 1.0.
Unless 3.0 fixes the reasons why 2.0 doesn't exist in the wide world, it'll just lead to more problems.
