Setting required for read_only question (with calculation)

Thanks, @Xiphware,
Same missing Enketo support for dynamic default. Would you mind to also adress the documentation issue in this context, please?

What do you mean with “null” here, please? At least a calculation may give an empty string, a NaN or InvalidDate, as far as we have seen…

We posted an ODK problem, partly related with UI and calculation here

Kind regards
