RFC 793, "Transmission Control Protocol", September 1981Source of RFC: Legacy
Area Assignment: tsv
Errata ID: 2771
Reported By: Mykyta Yevstifeyev
Date Reported: 2011-04-08
Rejected by: Wes Eddy

Throughout the document, when it says:
RFC 793 has no regulations whether it should obsolete RFC 761, which, however, is logically obvious. RFC 761 (http://tools.ietf.org/html/rfc761) is the previous version of RFC 793 and, if this errata report is verified, should be marked as obsoleted by RFC 793.
This is not a technical matter, and should refer to the RFC metadata rather than the document.
