Attribute synopsis
Description
A productionset is a collection of
Extended Backus-Naur Form (EBNF)
productions.
EBNF is a notation for describing the grammar of context-free languages. Even if you aren’t conversant in the programming language concepts of context-free languages and grammars, it’s not really as hard to understand as it sounds.
Processing expectations
Formatted as a displayed block. The detailed processing expectations with respect to individual productions, lefthand sides, and righthand sides are quite complex.
The productions should be numbered.

constraint, lhs, production, productionrecap, rhs
Examples
A set of EBNF productions describes the legal arrangements of tokens in a language. Consider arithmetic expressions as a simple example.
The expression 3 + 4 is valid and so is
3 + 4 - 5, but 3 - + - 4 is not,
nor is 3 + 4 6. We can use EBNF to describe all the
possible legal arrangements.
