I wouldn't worry so much about what the debugger says. Parsing will not
modify your document's infoset in any way, saving may. The debugger just
calls the .toString() method on XmlObject. Now this generic toString()
method has to work whether your document is parsed or modified or
created from scratch and have a sensible and easy-to-read result, but it
cannot be expected to return the perfect serialization for your
particular XML.

In practice, once you presumably make some changes to the document, you
would use XmlObject.xmlText(XmlOptions) to save it out, which gives you
more control over how the serialized form of the document looks.

So I would take what the .toString() method returns with a grain of salt
and not consider the namespace declarations indicative of what's really
in the internal representation of the document.
