[jdom-interest] xsi:nil

[Jason Hunter]

The prefix "xsi" doesn't mean anything without a URI associated with it, 
so you have to use the Namespace object to make the association.

Namespace xsi = Namespace.getNamespace("xsi", "http://...");
Element e = new Element("SampleElement);
e.setAttribute("nil", "true", xsi);
