My suggestion would be to read the old documents into a JDOM (see
jdom.org), do a deep iteration over each element, calling the
setNamespace() method.
From there, wrap the JDOM in a JDOMSource and pass that directly to
your JAXB Unmarshaller using unmarshal(Source).
Just avoid org.w3c.dom, that's a ghastly piece of work :)
