We have a task on our roadmap (after TCK completion)[1] to remove string processing from jbossws. In order to do this, we would need an enhancement to JBossXB that allowed parsing of DOM fragments. The best way to do this would be to add support for JAXP Source/Result objects as parameters. Then we have the option to either optimize a particular source ourselves, or if not known, we can simply delegate to the JAXP transformer. This is also required by JAXB, so if compatibility is still on the roadmap, it would need to be done anyway.
