Title : Constrained ABNF
Authors : Sean Leonard

Abstract:
This document extends the base definition of ABNF (Augmented Backus-
Naur Form) to express a rule that is constrained by another rule. If
a rule B is constrained by rule A, then every production generated by
rule B must also be generated by rule A. By creating subordinate
production forms, ABNF-using specifications can formally denote the
relationship between a general rule and specific subsets of that
rule, while preserving ABNF's context-free nature.
