Question

Answer 1

I believe I will use annotations on my domain if I am already decided with the persistence framework I am going to use, however, XML would be more convenient if you follow the Hexagonal architecture and TDD. If you annotate your domain with specific framework upfront, your will be coupled with the persistence integration and unable to test the core functionality with the aim of being technology/framework agnostic.
