SGML: Standardized Generalized Markup Language
Standardized Generalized Markup Language (SGML) is an international standard for the definition of system-independent, device-independent methods of representing text in electronic form. SGML is a metalanguage in which one can define markup languages for documents. XML is derived from SGML and now dwarfs SGML in terms of breadth of application. XML is a profile—a specific subset of SGML—designed to be simpler to parse and process than full SGML, and to have more lightweight internationalization. XML is a simplification of SGML for general-purpose applications.
