XSLT 2.0 courses?

Having seen XSLT course announcements here, I hope this is not an inappropriate question.

It turns out I have some work colleagues who need their skills expanded.

On the theory that sending someone to learn XSLT 3.0 before they've got the XSLT 2.0 concepts is neither kind nor useful, are there worthwhile, online, "You've been using XSLT 1.0 since forever, here's XSLT 2.0" courses still available?

Thanks!
