Yes, but it's not easy to build in such a generic fashion, mostly
because the contents that you propose to analyze are not machine
readable, but rather human readable. So you would need some sort of (God

Yes, but you could safely ignore the huge problem of understanding if
the attack is meaningful.

Actually, how to test IDS systems is, in itself, an open problem. Don't
