      Description

      A DESCRIPTION OF THE REQUEST :
      I propose adding a new interface with a meaning similar to Serializable. Any class implementing XMLEncodable would have to implement getPersistenceDelegate() and return a persistence delegate to encode itself.

      There would be three ways of encoding classes using XMLEncoder:

      1) Beans, they don't need a persistence delegate.
      2) Non-beans that do not implement XMLEncodable would have to associate a PersistenceDelegate with the XMLEncoder for the class
      3) Non-beans that implement XMLEncoder and provide getPersistenceDelegate().

      In all of the above cases, users can still override these delegates by calling XMLEncoder.setPersistenceDelegate() and providing a custom delegate.

      Methods 1 and 2 are currently supported by XMLEncoder. I am simply requesting we add method 3.

      JUSTIFICATION :
      Reduced overhead: As more and more non-bean core classes are supported under-the-hood by XMLEncoder for encoding, the internal Map of [Class, PersistenceDelegate] will grow. This new method will reduce the overhead of storing such a map.

      Increased ease-of-use: No need to associate PersistenceDelegates with classes that implement XMLEncodable. This would apply to 3rd-party classes, core classes, etc.

      Backwards compatibility is maintained
