[nsd-users] Prevent name compression on some RR types?

RFC 6742, section 2.4.1.2, says:

> A sender MUST NOT use DNS name compression on the FQDN field when
> transmitting an LP RR.

I do not see how to implement this with NSD 3. When I call
zadd_rdata_domain() in zparser.y, there is apparently no option to
register in the compiled zone database the fact that this must not be
compressed. As a result, the name is compressed, violating the RFC.

Such a rule seems to have been present only for DNSSEC-related RR
types until now. These DNSSEC RR types have a special handling in the
name server but I find nothing for other types.
