Hi Marc,
When I have a better idea of what is really missing or can't be worked around I will also post some of these things on the Oxygen list.
+1, please report back to us!
Although I understand that XQuery 3.1 wasn't official with the release of 17.1 earlier versions were a bit more relaxed about syntax.
Maybe Max, who did the work on Argon, can tell you more about it?
It seems that, even if I choose the BaseX connection for validation, the code still gets analyzed by Saxon 9.6
By "validation", do you mean the parsing of XQuery expressions? And with "connection", do you refer to the XQJ solution that we documented in our Wiki [1]? If yes, it’s Charles now who can possibly tell you more about this than me.
As you see, I have successfully passed on your questions to three other parties. Feels comfy, maybe I should always go on like this…
Christian
