So where is this documented?

The taglib URL doc is https://pd4ml.com/taglibdoc/
But as I see there is an inconsistence there with what I wrote above. I need to clarify that with the development.

Will including the pd4ml_tl.jar from pd4ml v3 allow us to use the new CSS / HTML / Accessibility features of v4?

Ah, no… PD4ML v3 API “knows” nothing about PDF/UA output option. But CSS/HTML new features are there.
