With all current server implementations I'm aware of, this probably 
won't matter as they do not enable namespace support. For a server which 
really supports namespaces correctly, this could break badly, as it will 
be looking for the nickname within the appropriate namespace, and not 
any node in any namespace with a local name of 'nick'.
When you add the element to the DOM tree, specify the namespace of the 
element as the namespace in which it belongs. When it serializes the 
DOM, it should only show it once. But by leaving the namespace empty, 
you are specifying that the namespace it is in is really "", and it 
specifies xmlns="" to indicate that it has changed the default namespace.
