Right.
There's an RFE filed in the issue tracker about writing a plugin that
would make the generated classes cloneable, but to my knowledge it
hasn't done yet (partly because of the problem of JAXBElement not
implementing cloneable.)
Perhaps one might be able to develop a similar plugin based on Ray's
idea --- the copy constructor.

Yeah, I think that would be a good work around. There's a global
customization to make all the generated classes serializable.

It doesn't exist today. I'm hoping that someone would volunteer to write
a plugin.
