Thanks Leen Besselink & Jan-Piet Mens.
I now have bit better understanding, related to DLV registry & DNSSEC.
So it should be added/done by the Authority (Alternative Root DNS
operator) who is maintaining (set of) TLDs, outside of icann/iana.

So for a better & successful DNSSEC validation, other than adding their
own DS, RRSIG records for set of TLDs, a TLD / AltRootDns operator needs
to add some of those record info inside DLV registry as well.

pls see my other email for other issues i'm having.
