New submission from Atamurad Hezretkuliyev <atamy...@gmail.com>:
Parsing "<test xmlns=''></test>" with minidom and converting back to string
raises an exception.
>>> import xml.dom.minidom
>>> xml.dom.minidom.parseString("<test xmlns=''></test>").toxml()
Traceback (most recent call last):

Ii am not familiar with the XML spec so I've no idea if ignoring or accepting
empty namespace is the right thing to do. If someone advices me on how it
should be handled, I'd like to write a patch.
