RFC 1035, DOMAIN NAMES - IMPLEMENTATION AND SPECIFICATION, November 1987
3.3. Standard RRs
The following RR definitions are expected to occur, at least
potentially, in all classes. In particular, NS, SOA, CNAME, and PTR
will be used in all classes, and have the same format in all classes.
Because their RDATA format is known, all domain names in the RDATA
section of these RRs may be compressed.
<domain-name> is a domain name represented as a series of labels, and
terminated by a label with zero length. <character-string> is a single
length octet followed by that number of characters. <character-string>
is treated as binary information, and can be up to 256 characters in
length (including the length octet).

RFC 4034, DNSSEC Resource Records, March 2005
6.2. Canonical RR Form
For the purposes of DNS security, the canonical form of an RR is the
wire format of the RR where:
...
3. if the type of the RR is NS, MD, MF, CNAME, SOA, MB, MG, MR, PTR,
HINFO, MINFO, MX, HINFO, RP, AFSDB, RT, SIG, PX, NXT, NAPTR, KX,
SRV, DNAME, A6, RRSIG, or (rfc6840 removes NSEC), all uppercase
US-ASCII letters in the DNS names contained within the RDATA are replaced
by the corresponding lowercase US-ASCII letters;
