Inheritance: Object BindingNotification

Remarks

This class is very similar to BindingValueT, but where BindingValueT is used by typed bindings, this class is used to hold binding and data validation errors in untyped bindings. As Avalonia moves towards using typed bindings by default we may want to remove this class.
