[ldns-users] SVCB and HTTPS support

[Willem Toorop]

Hi Niall,

Thanks for the heads up! You are correct. This is fixed in commit:

	https://github.com/NLnetLabs/ldns/commit/3373aa99

Would have been nice if the draft had some test-vectors of RRs in
unknown type format (RFC3597) and corresponding presentation format,
to test correctness of the implementation and also to improve
interoperability...

Maybe a nice contribution for in the upcoming IETF110 hackathon.

Cheers,
-- Willem
