I am not sure, what you really want to do. The DataHolder that is used by
default is created for every call to marshal/unmarshal so that the
converters may communicate within one (un)marshalling process.
If you provide a DataHolder yourself, you define how long this data is kept.
XStream.newDataHolder is a convenience method for *you* to provide an own
one, XStream does not call it.
Cheers,
Jörg
