Yes, this is right, so actually you found a bug. Can you enter this
as a bug in bugzilla, please.

Yes, but it's much safer to have the NamespaceNormalizingDOMStreamer
as default because of some severe bugs in Xalan; if you have namespaces
in your dom, it's safer to use the NamespaceNormalizingDOMStreamer.
As, in most cases you might not know if your DOM contains namespaces,
you have to use NamespaceNormalizingDOMStreamer anyway. That's why it
is the default. For performance reasons you can force to not use
the NamespaceNormalizingDOMStreamer.
