This I'm not sure of, I'll have to see an example.

This can happen when you declare the exolab namespace as the default
namespace in the mapping file, because the name attribute for bind-xml
is a QName, so the default namespace will be used for any names without
a prefix defined.
Eg:
<mapping xmlns="http://castor.exolab.org/ ...
xmlns:foo="http://foo.acme.org";>
...
<class name="...">
<field ...>
<bind-xml name="foo:bar"/>
<!-- exolab namespace will be used here because exolab namespace has
been
mapped as the default namespace uri -->
<field ...>
<bind-xml name="bar"/>
...
</mapping>

You can declare the default namespace on the Marshaller:
myMarshaller.setNamespaceMapping("", "ns-uri");
