        When I have a ConjunctiveGraph with the default namespace set,
        for example

        import rdflib
        g = rdflib.ConjunctiveGraph()
        g.bind(None, "http://defaultnamespace")

        then the Trix serializer binds the default namespace twice in its XML
        output, once for the Trix namespace and once for the namespace I used:

        print(g.serialize(format='trix').decode('UTF-8'))

        <?xml version="1.0" encoding="utf-8"?>
        <TriX
          xmlns:xml="http://www.w3.org/XML/1998/namespace"
          xmlns="http://defaultnamespace"
          xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"

        />

        """

        graph = ConjunctiveGraph()
        graph.bind(None, "http://defaultnamespace")
        sg = graph.serialize(format='trix').decode('UTF-8')
