I am trying to write a custom validator for an array field that contains a nested but flat object (my type adopts Content protocol).

Unfortunately, during the debugging, my custom validator methods are not hit, and the request fails with a validation error. It claims that this field is missing.

Are there any issues with array field validation in general, or more likely with my own validation in particular?

Finally, I send the data from the browser as a form: Content-Type: application/x-www-form-urlencoded.
