Comment:

 Hello

 Everything should be addressed except:

 Replying to [comment:11 jinmei]:
 > forgot to mention this: do we want to check when an SOA RRset is
 added/deleted
 > it has exactly one RDATA?

 Well, I don't think such change should be related to this branch. We might
 want to check that, and check that CNAME is the only one and so on…

 This branch wouldn't be the only thing that would act strange if there are
 multiple SOA RRs (considering they would have different serial, if they
 were the same, this branch wouldn't mind). But if you think it should, I
 have no problem adding the check. Anyway, I think this should be checked
 on some different level, because we can't do a complete check anyway
 (because add „merges“ with existing data anyway).

 Thanks
