Wirth syntax notation

Wirth syntax notation (WSN) is a metasyntax, that is, a formal way to describe formal languages. Originally proposed by Niklaus Wirth in 1977 as an alternative to Backus–Naur form (BNF). It has several advantages over BNF in that it contains an explicit iteration construct, and it avoids the use of an explicit symbol for the empty string (such as or ε). WSN has been used in several international standards, starting with ISO 10303-21. It was also used to define the syntax of EXPRESS, the data modelling language of STEP. (Wikipedia).
