Ray, thanks for sharing your thoughts, but your approach will cause maintenance headache. I would prefer using Serializable API then creating a copy constructor for every JAXB-generated class.

Hopefully it will not be an aggravation to you but.. I tend to shy away from the cloneable contract. That JAXB element you are referring to, at least in my systems, is really one of my objects that I am using JAXB to bring into existence from an XML file. Since that is the case I, like you, need to sometimes need to make copies of it. Both deep copies and shallow ones. Instead of using Clone I use simple copy constructors into which I pass a Boolean called, you probably guessed, deepCopy.
This allows me to avoid the cloneable contract and the ramifications of that (side effects).. I do not know if this helps you at all. But perhaps a different way of thinking on the subject might be in order.. Did you, or better said, can you consider the using of copy constructors instead of clone…
Once again I do not have your code in front of me and have little to go on expect for personal experience. Which I am sharing..

Subject: cloning JAXBElements
I need to create a "deep" copy of a JAXBElement which was constructed by JAXB during the unmarshalling process. None of the classes generated by JAXB implement clone() method from java.lang.Object. The ObjectFactory class generated by JAXB didn't provide any API useful for this purpose either.
However, I noticed that JAXBElement implements Serializable and I could potentially use this to implement object cloning by serializing and de-serializing the target JAXBElement instance.
What is the right way to clone a JAXBElement instance?
Thanks.
