[jdom-interest] additionalNamespaces

[rpcee]

the javadoc for Element.getAdditionalNamespaces() says it excludes the element namespace, but in the case of a document built via SAXBuilder, it returns all namespace declarations for that element, eg:

final String xml = "<n:root xmlns:n='uri1' xmlns:z='uri2'/>";
doc = new SAXBuilder().build(new StringReader(xml));
System.out.println(doc.getRootElement().getAdditionalNamespaces());

displays:

[[Namespace: prefix "n" is mapped to URI "uri1"], [Namespace: prefix "z" is mapped to URI "uri2"]]

I think it's a consequence of the commented out code in SAXHandler::startElement(), and the fix is that SAXHandler::transferNamespaces() needs something like:

if (ns != element.getNamespace()) {
   element.addNamespaceDeclaration(ns);
}

?
