Observaciones:

In a data binding scenario, use the Value property as the binding source path for controls of the view and the field name specified in the Field property to associate validation rules and errors for this field element. So when Binding requests GetErrors() for errors for the bound property Value the errors associated with Field are returned and when it is required to notify changes in the errors of the field The ErrorsChanged event is raised for the Value property.
