Hi Stephen,

This IMO should be coordinated with Cinder, who also uses suds. Please
make sure that both projects are moving on the same direction, using the
same library for these XML stuff.

It's been a long time I've been saying we should get rid of that one
library which has historically been very annoying. I'm very happy to
finally see movement!

Cheers,

Thomas Goirand (zigo)
