LDH is a nice name (although "traditional host name syntax" is more
common) but I suggest to change the references. RFC 1034 section 3.5 or
RFC 1035, section 2.3.1, do not define LDH, they just reuse
traditional host name definitions (which are now in RFC 1123, section
2.1).

AFAIK, there is not one authoritative RFC where you can find the
official grammar for the "traditional host name syntax", LDH. Even RFC
1123 is written (on this point) as a diff to RFC 952.
