You're spot on, Milo - the part of dhcp6 being the option space was missing. In
hindsight, it is pretty obvious now that I see that working fine. Not sure if
the images / attachments get stripped by the mailing list but the outcome is as
expected ? I now have Option 56 showing up in the server response. Pretty neat.
I wish this part of having to use dhcp6 as the option space was documented in
manpage somewhere. I would have saved a few days of searching and experimenting
and getting frustrated
Much appreciated!

Oh, I'm sorry. The sntp-servers is option 31.
I think vendor-option-space is not necessary. It is for custom vendor options
e.g. if one vendor use option code 10 and other vendor use the option code 10
too but with different meaning. I would try:
option space ntp56 code width 2 length width 2 hash size 2; option
ntp56.address code 1 = array of ip6-address; option ntp56.fqdn code 3 = text;
option dhcp6.ntp-servers code 56 = encapsulate ntp56;
ntp56.address = fc00:6ce4:40:146::1;
ntp56.fqdn = "ntp.example.com";
Would like to test, but none of our of thousands clients does not require this
option.
