Hi all, I'm trying to write some documentation for users of Let's Encrypt about CAA. I believe it's the case that standards-conformant authoritative resolvers should return NOERROR for qtypes they don't recognize, rather than NOTIMP. Is this correct? If so, what is the relevant standard? I haven't been able to find a citation in https://tools.ietf.org/html/rfc3597, https://tools.ietf.org/html/rfc6895, or https://tools.ietf.org/html/rfc1035.
Thanks, Jacob
