Re: [libvirt] [patch 4/5] nwfilter: Extend schema to accept state attribute

Hum, we really want to accept something like

I understand that we may want to add RELATED to another state, but that
regexp could probably be refined, isn't it ?


I think the proposed solution is not as 'strict' as it should be but
compared to the other two
solutions I think it is 'ok' -- unless there is a fundamentally different
way of writing this
type of regex.

I agree with Stefan's point of view: the .rng should be a syntax check and outlaw completely unrecognized words, but to be concise, it is necessarily loose and requires that we then perform additional semantic checks to reject strings like NEW,NEW. And this is evident in my recent <vcpu cpuset=...> patch, where domain.rng accepts strings like cpuset='4-3' as syntactically valid (a range of integers) that are later rejected by semantic checks (the integer range is backwards).
