  Fawcette.com - Understand Extended BNF   (Site not responding. Last check: 2007-11-06)
Without realizing it, you have probably encountered some of the EBNF symbols while reading the Java or other languages' specifications, but you will deepen your understanding of the language if you know what these symbols mean.
EBNF is the definitive choice because a grammar defined using it is precise, concise, and unambiguous, unless the language itself is ambiguous.
Naur then decided that there must be a uniform set of symbols that could be used to define the grammar of a language, and drew up on his own notation—BNF—for ALGOL 60.

When Niklaus Wirth was developing Pascal, he simplified Backus-Naur Form to create EBNF.
All these constructs can be expressed in plain BNF using extra productions and have been added for readability and succinctness.
The W3C used a different EBNF to specify the XML syntax.

 Zvon - RFC 1138 [Mapping between X.400(1988) / ISO 10021 and RFC 822] - Chapter 3 -- Basic Mappings
When these EBNF tokens are referred to outside an EBNF definition, they are identified by the string "822." appended to the beginning of the string (e.g., 822.addr-spec).
For each case, an EBNF syntax definition is given, for use in all of this specification, which leads to a mapping between ASN.1, and an EBNF construct.
All EBNF syntax definitions of ASN.1 types are in lower case, whereas ASN.1 types are referred to with the first letter in upper case.

 RE:Content markups, EBNF & DTD   (Site not responding. Last check: 2007-11-06)
If you also had the associated specification (prose), then you would be able to infer the semantics of the elements and their attributes (among other objects) in the document.
Furthermore, if you also had the EBNF, then you would know whether you should have the document correspond to XML 1.0 (or some other version).
So the knowledge of EBNF is necessary to author a document that conforms with the XML 1.0 Specification.

 International Standard EBNF Syntax Notation   (Site not responding. Last check: 2007-11-06)
The Extended Backus-Naur Form (EBNF) adds the regular expression syntax of regular languages to the BNF notatation, in order to allow very compact specifications.
Numerous variants of BNF and EBNF have been introduced and practically every compiler-design textbook and programming-language standard defines its own version.
While a BNF notation can be specified in a few sentences, the proper definition of EBNF requires a little bit more explanation, and therefore frequently only BNF is used although the result is much less readable.

 BNF and EBNF: What are they and how do they work?
Just for the record: EBNF is not more powerful than BNF in terms of what languages it can define, just more convenient.
Any EBNF production can be translated into an equivalent set of BNF productions.
EBNF is also used in many other standards, such as definitions of protocol formats, data formats and markup languages such as XML and SGML.

 Introduction
Inline EBNF grammar specifications can mix freely with other C++ code and, thanks to the generative power of C++ templates, are immediately executable.
In retrospect, conventional compiler-compilers or parser-generators have to perform an additional translation step from the source EBNF code to C or C++ code.

 Notations for context-free grammars: BNF, Syntax Diagrams, EBNF
Something more like EBNF (see below), but nearly as space-filling as syntax diagrams, was also used for COBOL.
Like syntax diagrams, EBNF does not allow us to write anything that can't be written in BNF, it just makes the grammar easier to understand.
Given that the only reason for using EBNF instead of BNF is to simplify and clarify language descriptions, it would seem sensible to provide all these facilities, and maybe others as well (e.g.
