RFC 2738 Corrections to Syntax for Media Features December 1999
1. Introduction
In RFC 2533, "A Syntax for Describing Media Feature Sets" [1], an
expression format is presented for describing media feature
capabilities using simple media feature tags. This provides a format
for message handling agents to describe the media feature content of
messages that they can handle. That memo also describes an algorithm
for finding the common capabilities expressed by two different
feature expressions.
This memo contains two corrections to that specification: one fixes
an error in the formal syntax specification, and the other fixes an
error in the feature set matching algorithm, in the rules for
reducing feature comparison predicates.
The first of these corrections affects the normative content of RFC
2533; the second affects non-normative content.
1.1 Terminology and document conventions
This specification uses syntax notation and conventions described in
RFC 2234, "Augmented BNF for Syntax Specifications: ABNF" [2].
