The current attitude in the standards community appears to be that zone
configuration is "too hard", "too complicated" and/or "too
security-sensitive" to be handled by Dynamic Update. Therefore the most
you can do via the Dynamic Update protocol extension is to create the
delegation records from the parent zone. The creation of the subzone's
"nucleus" (SOA and NS records) needs to be accomplished in some other
way, after which you can use Dynamic Update to populate the rest of the
subzone's contents.

Occasionally there is some talk of including zone-creation (potentially
also zone-deletion) in some sort of "provisioning" protocol, but so far
it's just talk.
