Where to find all the options for /etc/config/dhcp file?

[NAVras]

There are many options shown in Wiki [1] [2], but LuCI has a "local IPv6 DNS server" that corresponds to dhcp option dns_service in the file, which I can't find in the Wiki.
Where can I find the complete options for /etc/config/dhcp file?

I'm trying to migrate the settings from dnsmasq+odhcpd-ipv6 to odhcpd (ipv4+ipv6).
EDIT: Silly me... no conversion required except enabling maindhcp

On the source code

There are a few options to set DNS server, examples:

list dhcp_option '6,192.168.1.2'
list dns 'fdfa::253'
list dns '192.168.1.2'

That option is not supported in the current stable release:
https://openwrt.org/docs/techref/odhcpd#documentation

Someone is required to update documentation for the upcoming release:

Which option isn't supported?

[NAVras]

I guess all the options that are present in the snapshot README but not in the 19.07 README (current Wiki doesn't have some of the options in 19.07).

Added: dns_service, preferred_lifetime, ra_flags, ra_slaac
Removed: ra_management
