Hi Rogier,
I think, your reasoning is quite correct. To note, this is not a bug
in the maven-jaxb2-plugin, it is more a problem with XJC itself.
maven-jaxb2-plugin only wraps XJC.
I'm also coming over this issue time after time. I always managed to
resolve it somehow, but I can't formulate the method at the moment.
Would you please put a sample demo project together - I'll look into
it. We'll probably have to file an issue for XJC since I don't think
this can be fixed in the Maven plugin.
Bye,
/lexi
