All these go to reg as description of items.
Both - reg and reg-names - need constraints per variant in allOf:if:then:. Move allOf: to bottom of file, just like example-schema is showing.

I don't think you need it.

This should be maxItems.

I guess as well.

Just true.
Please open existing, recent PCI bindings and look how it is done.

This also needs cleaning.

Misaligned.

Use defines for common constnats.
