minidom toxml() not emitting attribute namespace qualifier

[kevin]

Using Python 2.2.3, with this example code:

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()

The output is missing the "myns" namespace qualifier on the "att"
attribute. Can someone tell me what I'm doing wrong?

Thanks, Kevin
