I have also noticed, if you don’t put DS records in the parent zone, then you can DNSSEC enable your zone, check the records are properly signed, etc… but because the glue is missing, then your zone is not “secured”. It means the resolver won’t care if the signatures are valid or not (unless you load the DS keys in your resolvers). So check that your software roll out the keys correctly a couple of times, before you add the DS in the parent zone this sounds like a correct very controlled roll out: http://www.auda.org.au/industry-information/au-domains/dnssec/ This is a neat tool to check everything: http://dnsviz.net/d/edu.au/dnssec/ and http://verteiltesysteme.net/ allows you to check your resolver is working correctly
