Natural JAXB support for interfaces

[Tomas-Kraus]

I would like JAXB to support interfaces natively without workarounds or XmlAdapters. Though I am not familiar with the spec, it seems like JAXB should follow the following procedure when unmarshalling a class:

1. Unmarshall using Class.newInstance(). 2. If #1 won't work, search for the factoryClass and factoryMethod attributes of the XmlType annotation and use those to generate the object. 3. If #1 and #2 won't work, search for the ObjectFactory for this package and find a method returning the desired type. 4. If all 3 steps fail, report an error.

This feature would make JAXB easier to learn and easier to use. If this is in conflict with the spec, I would request that this be added as a vendor-specific feature.
