 Allows recursive validation of sub-objects in a class when using [DataAnnotations validation](https://docs.microsoft.com/en-us/aspnet/core/mvc/models/validation?view=aspnetcore-3.1) (also known as Attribute Validation).

Therefore it is necessary to add some glue code to recurse through the object graph.
