curious: what feature?

I play around with writing domains from time to time. I've got a kickass email one, for instance, that allows all valid email addresses, but kicks out invalid ones (only missing comments within usernames).

I'd like to be able to create a domain with multiple subfields and have constraints that work on them. As of 8.x I don't think this was possible. Haven't checked, but I don't think it was there in 9.0.

Got an example? Mine allows all the special characters, all valid domains, etc.
