The idea behind force was, that imagine two virshes running. In both you
start editing the same domain. In one you successfully save the changes
and domain XML is regenerated. However, the other one notices this and
ask you, that domain definition has changed meanwhile, if you want to
continue. And by choosing 'force' you can use the force, Luke.

What could happen to the EDIT_RELAX to be undefined? I mean, it'll be
defined no matter what (since you're defining it here in this patch).
