Hi Romano,
Actually the order of attributes does matter.
Ok, fair enough. Would be nice to remove the order dependencies for XML
compliance, but it's not so urgent, I agree (I would love to be able to
work on other things that would be especially nice...).
By the way, if anyone need it (it needs python 3.4 I think), the script
to replace the bg is attached here (I hope it will go through the list).
Run with -h to have the help and options.
