[...] BNF (Backus Normal Form or Backus–Naur Form) is a notation technique for context-free grammars, often used to describe the syntax of languages used in computing, such as computer programming languages, document formats, instruction sets and communication protocols.

[WIKI_XML]
This specifiation provides a language for expressing BNF grammars in XML. This shall enable processing of BNF grammars with XML based tools. The use case in mind is markup of BNF in specifications which are written in XML based languages such as XHTML or DocBook. However, other use cases might exist and are not excluded by this specification.
There are many different variants of BNF. BNFML 1.0 is designed with three variants in mind: [XML_NOTATION], [ISO/IEC 14977:1996], [RFC5234].
