Yes, this is what you need.

Yes this is correct, they are located in the foo zone (same domain_id as the 
SOA record mentioned earlier).

This is an option. However depending on the number off records and your needs 
it might be easier to:
A. include the records directly in the foo zone without adding a separate zone 
(with its own SOA records and NS records)
OR
B. put them on separate name servers

Don't forget that you need to add NS records to the foo zone for the domain and 
in the domain zone. For this you can also check the domain_id field.

Do you want to also support DNSsec? This is possible with PowerDNS, you need to 
add DS records for the domains. If you provide an EPP service to your 
customers/registrars this is easy as they can provide the DS records. It would 
be a nice service to verify the DS records at the time they are provided to see 
if they match and if not return an error or warning.

Let us know if you have other questions.

Kind regards,

Mark Scholten
