title: XJC superinterface and superclass only for all classes?
body: <p>I'm trying to automatically implement an interface in one java class generated from a xsd file.</p>
  
  <p><a href="http://docs.oracle.com/cd/E17802_01/webservices/webservices/docs/2.0/jaxb/vendorCustomizations.html#superinterface" rel="nofollow noreferrer">This</a> looks as if it could do that, but it will only add <code>implements SomeInterface</code> to all classes, which is completly stupid. Am I missing something or can you only do this for all classes? Doesn't really make too much sence to let all generated classes implement the same interface. Can I use this feature for one class only? </p>
