Have a look at the following in order to activate the creation
of default attributes:
http://mail.gnome.org/archives/xml/2006-May/msg00020.html

And have a look at the following in order to make it work, since
there was a bug which was fixed just yesterday! Use the CVS HEAD.
http://mail.gnome.org/archives/xml/2006-May/msg00051.html
There might be still some more bug in this mechanism; it's really
not well tested, plus we have no regression tests for this. The
W3C XML Schema tests suite, has also no support for testing
creation of default attributes. So feedback is appreciated :-)

I haven't looked at the code you supplied and I don't know if
setting the validation options is possible through the Python
bindings (is the function exported to Python?).
