Give it a try @hoehrmann and if you find anything else, feel free to open another issue

Thanks for reporting @hoehrmann, I just tried it with the latest main and seems to be working just fine,

There is an issue with this month's release v24.3 and v24.3.1.

Okay, and thanks for the quick reaction!

FWIW:

The schema might be an interesting test case for xsdata, the generated code cannot be loaded due to circular imports, and some of the code looks a bit weird (though as a first time user I have no reference for what to expect). I suspect the schema is a bit unusual because they also derive a JSON Schema from it. The pattern that causes the circular import is a base type that is a union of foo: list-of-foo, bar: list-of-bar, ... and then there are Foo and Bar that derive from the base and restrict it to their corresponding list (so the base type needs the derived types, and the derived types need the base, hence a circular reference). The properties could be erased from the base, they never really exist there. This might also be causing some Anys that seem odd to me.

[tefra]

At the moment xsdata doesn't know if the generated code has circular imports, but it comes with different structure styles that can resolve this issue.

I took the liberty to add the suite in the samples repo, I used clusters and that took care of the circular import issues, there were a few issues that were resolved here

You can check it here, with some notes about some further limitations with mypy

https://github.com/tefra/xsdata-samples/tree/main/sdmx_ml, check the .xsdata.xml config I used
