You are confusing SSL and DNSSEC. Both use the same
underlying public key cryptography techniques. They just
package them up diffently.
For DNSSEC you using dnssec-keygen to create the key and
dnssec-signzone to sign the zone. You pass the DS RRset
to your parent zones administrator for them to sign so they
can make a secure referral to you. If your parent is not
yet signed you can send the DS RRset (or DLV RRset) to us
and we will include it in the DLV tree. It's a trival
matter to convert from DS to DLV as only the name and type
code are changed.
If you send us your DS/DLV RRset then when your parent start
signing their zone you need to tell us to remove the DLV
RRset and to send the parent zone the DS RRset.
