Working impl of AbstractMessage / Message concept

when using "superclass for generated code, subclass to enhance/override behaviour" - concept, then generated, nested "final" types are _evil_!
The types should not be in the abstract base class, but on the acutal class the API user will use. but this class is not being generated (only inhertis the generated class) but types are not being inherited, nor can you subclass them into the subclass because they are final.
