Therefore, we should consider to introduce another validator. During the migration phase, we have used **jing**. It's Java, it's fast, the error messages are very precise. But there are many others:https://relaxng.org/#validators. Should we possibly provide multiple validators in doc/src/sgml/Makefile?
If you follow the links on that page, it appears that all the projects other than jing are abandoned. Even jing has a very sporadic release history (2015 -> 2018 -> 2022). Last year at FOSDEM I gave a talk about the state of the DocBook toolchain [0], where I found that there is pretty much no tooling available for Relax-NG. So it's great that there is a 2022 release of jing, but before we can consider relying on that, it might be nice to see a bit more of a track record. (And we should also wait a little to make it trickle in stable packages for common operating systems.)
