XOM API for Processing XML with Java

[Nils_Kilden-Pedersen AT Countrywide.Com]

I have this XML:
<?xml version="1.0" encoding="UTF-8"?>
<root xmlns:xi="http://www.w3.org/2001/XInclude";>
        <xi:include href="some.xml"/>
</root>

Is this incorrect use of XInclude? 

XOM throws this exception:
Exception in thread "main" nu.xom.NamespaceException: Attribute objects 
are not
used to represent  namespace declarations
        at nu.xom.Attribute.setNamespace(Attribute.java:407)
        at nu.xom.Attribute.<init>(Attribute.java:150)
        at nu.xom.Attribute.<init>(Attribute.java:116)
        at nu.xom.converters.DOMConverter.convert(DOMConverter.java:186)
        at nu.xom.converters.DOMConverter.translate(DOMConverter.java:91)
        at test.Test.main(Test.java:40)


Thanks,
Nils
