Each generated java file should contain a header that specifies the
version of JAXB used to create it. I think we also bake the version
info into the class files in a way that you could programatically
access it, but I'm not sure how off the top of my head. I'd have to
go look...

"xjc -version" should work, if it doesn't, then you are using 1.0 and
should upgrade ;8-)
