In my experience null and empty in DTOs usually play the same 
logical role. It's a very contrived technical difference without 
practical usage, such distinction is way beyond any business 
logic. Even if you implement this distinction, I'm not sure 
anybody will carefully pay attention to it. In languages that 
make difference between null and empty, null is often replaced 
with empty to work around problems with null, such codebase can't 
properly preserve null values.
