The parser expects a well formed XML file. So you must have a
well-formed XML file if you want to unmarshal it in Castor. The most
common solution is to wrap everything in a root element and then strip
off this root element during unmarshalling by using your own
ContentHandler and then forwarding all other events on to the
UnmarshalHandler.
However, you could also pass in a Vector as the root object, as long as
you have a good enough mapping file so that Castor can correctly find
all child elements based on element name.

Just set this at the start of marshalling:
marshaller.setNamespaceMapping("xsi",
"http://www.w3.org/2001/XMLSchema-instance";);

Use the above.
