 class MyDocument(BaseDoc):
        caption: TextDoc



MyDocument(caption='A tiger in the jungle')

this will fail bc I did not find a way yet to override pydantic validation for BaseDoc

many test are skipped because of this example:

Many of tests/predefined_document failed for this reason. (search for skipif inside the folder to see which one).

Hint: to solve this one we need to highjack pydantic validation to convert the single value into a dict. We are already doing this with pydantic v1 but since pydantic v2 validation has partially been moved to the pydantic_core package it is less obvious how to do it.

Obviously, in python we can always make it work, the question is how to make it work so that it will still be aligned with pydantic guardrails regarding validation
