add namespace to java dom attribute

Question

I am trying to create an attribute with a namespace prefix. The following code does not seem to work:

Element newData = docFromXML.createElement("Data");
Attr typeAttr = docFromXML.createAttributeNS(namespaceContext.getNamespaceURI("ss"), "type");
typeAttr.setValue("String");
newData.setAttributeNode(typeAttr);

I expect the following:

<Data ss:type="String"></Data>

But the following is produced:

<Data type="String"></Data>

How do I explicitely add the namespace prefix "ss". The getNamespaceURI function returns the URL for the ss prefix in the DOM.

I think I have figured out why it does not work. ss happens to be the default namespace in the root of the same DOM: <Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" xmlns:html="w3.org/TR/REC-html40"> So how do I still add it explicitly? I still need it there. — U-L

The following works:

Attr typeAttr = docFromXML.createAttribute("ss:type");

It generates:

<Data ss:type="String"></Data>
