Should it be able to return both kinds of errors at once?

[aaron-collier]

I don't think that's possible, at least as written. The multiples requires the top level value to be present and it's not when blank. Perhaps this is a topic for follow up discussion with @andrewjbtw or @arcadiafalcone

Wondering if this is the sort of change we might want to run against a sizable subset of prod data to see how this affects validation.

[justinlittman]

This should be validated against all items in all environments else chaos ensues.

[aaron-collier]

@mjgiarlo / @justinlittman agreed. I've marked as hold.

[jcoyne]

@aaron-collier how long will this take to validate? We're getting hammered with these errors again/still.

@andrewjbtw here is a list of the druids that vail cocina validation with this change. 1073 objects. Should these be remediated before this change goes in?

Removing hold per @andrewjbtw:

I think these are all fixed. I’m not sure what will happen if MARC-origin updates trigger this issue after we turn on the validation, but I don’t see how we can chase down where those past errors came from. It’s worth turning on the validation for spreadsheet imports and then seeing how we can catch the MARC-related issues if they happen again.

@mjgiarlo / @justinlittman ready for a follow up review.
