Problem/Motivation

I am working on a complex field widget that sets #required on a certain property. This causes an error when using the "Remove" button on a multiple-value field if the property is empty (in this case, using #limit_validation_errors is not possible). I would like to be able to add a custom validator using #element_validate to remove the #required_but_empty property set during form validation and prevent errors from being set.

Otherwise, I would have to implement my own validation to ensure the field is not empty, add the required marker to the form label, add required properties to the element attributes, etc.

Steps to reproduce

Proposed resolution

During form validation, check for #required_but_empty to set errors.
