problem is this is the way it was done in Jaxb1 and my application is
running with that. Now i am migrating this to jaxb2.0 and i cannot change
the XSD. What can i do now ?
Is there any way to define external binding to add values for enum that are
not in XSD? or any other work around to overcome this ?
Thanks and regards,
Rochak
