$instance The instance structure for $field on $object's bundle.

$items $object->{$field['field_name']}, or an empty array if unset.

$errors The array of errors, keyed by field name and by value delta, that have already been reported for the object. The function should add its errors to this array. Each error is an associative array, with the following keys and values:
