Backus–Naur form One common feature of many variants is the use of regular expression repetition operators such as codice_19 and codice_20. The extended Backus–Naur form (EBNF) is a common one. Another common extension is the use of square brackets around optional items.

Augmented Backus–Naur form (ABNF) and Routing Backus–Naur form (RBNF) are extensions commonly used to describe Internet Engineering Task Force (IETF) protocols. Parsing expression grammars build on the BNF and regular expression notations to form an
