The ENBF is important indeed. However, not that much parsing tools use
the Extended BNF. Most of them are YACC-like variants or regular BNF.
There is an arguement on the shift-reduce or reduce-reduce conflicts
that tend to occur more often in EBNF grammars.


There is some tool named "ebnf2yacc" you can experiment with.
Personally I use the "GOLD Parser Builder" which uses regular BNF.
