bnf extended

基本解釋

My works maintains: the first is to change the extended BNF of TTCN-3 into the normal BNF;
我的工作主要有：一是對TTCN-3的擴展語法規(guī)則范式進行改寫；
The grammars for complex languages are commonly described using BNF (Backus-Naur Form) notation or its close relative, EBNF (Extended BNF).
復(fù)雜語言的語法通常都是使用 BNF（巴科斯-諾爾范式，Backus-Naur Form）表示法或者其“近親”― EBNF（擴展的 BNF）描述的。
Syntax Notes: In this and the following chapters, extended BNF notation will be used to describe syntax, not lexical analysis. When (one alternative of) a syntax rule has the form.
句法注意：在本章和之后的章節(jié)中，描述句法時使用與詞法分析時不同的擴展BNF記法。當(dāng)某個句法規(guī)則（可能是可選的）具有如下形式。
