Implementer-Friendly Specification of Message and MIME-Part Header Fields and Field Components
RFC 4249, “Implementer-Friendly Specification of Message and MIME-Part Header Fields and Field Components”, is an Informational document published in January 2006 by B. Lilly. The canonical text is published by the RFC Editor.
Abstract
Implementation of generators and parsers of header fields requires certain information about those fields. Interoperability is most likely when all such information is explicitly provided by the technical specification of the fields. Lacking such explicit information, implementers may guess, and interoperability may suffer. This memo identifies information useful to implementers of header field generators and parsers. This memo provides information for the Internet community.
What “Informational” means
