Section 2.3 says:
This record would indicate that "foo://api.example.com:8443" is aliased to "svc4.example.net". The owner of "example.net", in turn, could publish this record: svc4.example.net. 7200 IN SVCB 3 svc4.example.net. ( alpn="bar" port="8004" ) This record would indicate that these services are served on port number 8004, which supports the protocol "bar" and its associated transport in addition to the default transport protocol for "foo://".
It should say:
This record would indicate that "foo://api.example.com:8443" is aliased to "svc4.example.net". The owner of "example.net", in turn, could publish this record: svc4.example.net. 7200 IN SVCB 3 svc4.example.net. ( alpn="bar" port=8004 ) This record would indicate that these services are served on port number 8004, which supports the protocol "bar" and its associated transport in addition to the default transport protocol for "foo://".
Notes:
As far as I understand the rest of the RFC as well as the other examples provided, the port must not be quoted as stated in 7.2 ("port"):
The presentation value of the SvcParamValue is a single decimal integer between 0 and 65535 in ASCII.
[WK: Rejecting this errata with a note from the DNSOP list: https://mailarchive.ietf.org/arch/msg/dnsop/BHLZtTaDLiHcMWe2NDnl_HJ0RwM/
Text:
"This report is incorrect. SvcParamValues always are presented via a char-string encoding as defined in Appendix A, so quotes are always allowed. The "single decimal integer" applies to the "value" which is derived by reversing the escaping of the char-string, producing a *OCTET in ABNF.
Thanks for the close read!
