Given a DOM tree, any (un)marshalling you can define in terms of
mappings of an XPath to some java.lang.Class and the relation between
the element's children to the proeprties of the class is feasible. It's either
out of the box (using javax.xml.bind.annotation..*) or some binding
feature, or one of the plugins.
Honestly, I don't quite see what you'd like to have. Can you formulate
it in terms of JAXB/XML Schema/XML alone, leaving Jersey aside?
