See my results below.

Not any more, apparently - see below.

Well, it was definitely there in the 2.1 series, but as my recently
added comment on SourceForge suggests, I think it has been resolved in
recent minidom implementations. Certainly, I don't think that my
particular installation of Python (Cygwin, Windows 2000, Python 2.2.3)
has any additional modifications, and yet...

>>> import xml.dom.minidom
>>> XML = """\
... <?xml version="1.0"?>
... <elem xmlns:myns="mynamespaceuri" myns:att="value"/>
... """
>>> dom = xml.dom.minidom.parseString( XML )
>>> print dom.toxml()
<?xml version="1.0" ?>
<elem myns:att="value" xmlns:myns="mynamespaceuri"/>

Am I missing something or is this not what one would expect?
