It's just nonsense. In the IETF's nomenclature, the label "Internet Standard" is used to refer to, and I quote: A specification for which significant implementation and successful operational experience has been obtained may be elevated to the Internet Standard level. An Internet Standard (which may simply be referred to as a Standard) is characterized by a high degree of technical maturity and by a generally held belief that the specified protocol or service provides significant benefit to the Internet community. A specification that reaches the status of Standard is assigned a number in the STD series while retaining its RFC number.
