Try this:

    // Either:
    Namespace rootns =
Namespace.getNamespace("http://www.govtalk.gov.uk/taxation/CodingNoticeP
9");
    // or:
    Namespace rootns = myRootElement.getNamespace();
    
    Namespace ns1 = Namespace.getNameSpace("ns1",
"http://www.govtalk.gov.uk/gateway/digitalmail");
    Element ref = parent.getChild("Reference", ns1);
    ref.setNamespace(rootns);

The trick here is not that you want the Reference element to have no
namespace but rather that you want it to be in the same namespace as its
parent, which turns out to be the default namespace set on the root
element.
