Hello! Thank you for your contribution! The main purpose of these examples is demonstration of code behavior, I think that such additions make readability worse.

If you are interesting to exclude possible errors with exception skipped, there are idea to use pytest.raises() context manager inside examples. I have some doubts about this way since documentation examples start look like tests but pytest primitives should be clear to any reader.

I think that such additions make readability worse.

Current code says: ignore ValidationError if it happens.
My version says: ValidationError must happen here.

Anyways, I don't really have a strong opinion about it, so feel free to close :)
