This document describes an ABNF extension for code generation.
The extension has two features; extension rule and non-sequence group
notations. The extension rules are used to direct the parser
generator with things like data types, variable names, forced value
for a variable, etc. The non-sequence group feature was proposed as
part of RFC 2234 in the past, but dropped due to its ambiguities.
The feature is proposed again in this document not as a fundamental
building block, but as an add-on. The elements of a non-sequence group
are unordered, and are allowed multiple appearance.We attempt to
minimize the ambiguities stemmed from repetition of an element by defining
specific repetition rules for elements of a non-sequence group and
non-sequence group themselves.
