xml is order-sensitive and in some cases we just have to deal with
that - because in order to tell the DTD not to care, you end up
loosing any benefit of doing the DTD validation.

unfortunately the people that wrote the GUI didn't take much notice of
the interfaces of the thing it was supposed to configure and you end
up with these sorts of problems.

fyi: dtd validation _can_ be turned off by setting
   <cib ignore_dtd="false" ...>
in your configuration.

BUT BE VERY CAREFUL!
There are good reasons we turn it on by default :-)
