xmlns: is a prefix with a special meaning: it defines an xml namespaces
prefix. you should read about how they work.

The following:

Element('{http://www.w3.org/2001/XMLSchema-instance}my_node_name')

will generate a proper xmlns declaration for you. It may not be the same
every time, but it will do the job just as well.

btw, if you need to generate xml schemas, have a look at spyne:
http://spyne.io

Specifically:
https://github.com/arskom/spyne/blob/master/examples/xml/schema.py

best,
