I want to know how to describe XML in the form of a Grammar.  I am not sure if it is a COntext free Grammar or a meta Grammar.  I need to know the specfication for an XMl Context free gammar.

XML Context free grammar

A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard), while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common.

Extensible Markup Language (XML) refers to the encoding of documents such that they can be read by both machines and humans. XML documents use tags to show the beginning and end of a set of data. XML is used extensively on websites to show volumes of data, and is the default for a number of office productivity suites. This topic includes discussions of XML-related technologies, such as XQuery (the XML Query language), XPath (the XML Path language), XSLT (eXtensible Stylesheet Language Transformations), XLink (the XML Linking language) and XPointer (the XML Pointer language).
