There's no support for this in XStream. XStream is "from Java to XML and
back" and therefore not designed to keep unknown elements, because they are
not part of the Java model. Either you enhance your model or you may have a
look at XSTR-474. Peter Knego once developed an enhancement with a similar
functionality with certain limitations.
Cheers,
Jörg
