And if you pass it 

public class EmptySource implements Source{

	private String systemId = "http://www.example.com/myidentifier";;


	public void setSystemId(String systemId){ this.systemId =
systemId; } 
	
	public String getSystemId(){ return this.systemId; }
}

what does it do? After all this class faithfully implements the Source
interface.

There is one advantage. If you hand the transform() method a Date, or a
List, or a Gremlin, you will get a compile time type error. For me,
that's a good enough reason to invent a marker interface rather than
using Object.
