If today it's "A,C,E" or "A-E,^B,^D", then why not devise a way to use "0,~0" meaning 0 and the one's complement of 0 (e.g. everything else). That way if I wanted to, I could "0,~0,^4" meaning everything except 4. Of course the downside is that I need to know what the guest maximum is. The only way to know that is in post parse processing. So doing this may involve moving the translation of @nodeset and @cpuset...
