I used sxml [0] unironically in this project extensively.

The rendering step for reports that humans got to see was a call to pandoc after the sxml was rendered to markdown - look ma we support powerpoint! - but it also allowed us to easily convert to whatever insane markup a given large (or small) language model worked best with on the fly.
