XSLT Debugging with Saxon supported?

[cmahnke]

It's not quite clear if this plugin support this, but is it possible to debug local XSLT stylesheets using Saxon?
In a recent IntelliJ I'm not even able to add a debug configuration while running and profiling works as exspected.

Since the tag line states:

XQuery 1.0-3.1, XPath 2.0-3.1, XSLT 3.0, and XProc 1.0-3.0 language support with BaseX, MarkLogic, Saxon, and W3C extensions; run, debug, and profile queries; and more.

I assumed that this should work.

Or is there a special requirement which isn't documented? I'm currently using saxon-he-12.4.jar.
