Log message

NSXML doesn't output the default namespace (via XMLString) if it was set via
setURI:.  To get around this but I was manually adding an attribute named
"xmlns".  Now switching to using addNamespace: and supplying a namespace created
with an empty string prefix. This is the correct way to do it.
