XML is designed to enable the use of SGML on the World Wide Web. XML is not a single, predefined markup language: it’s a meta-language—a language for describing other languages-which lets you design your own markup. (A predefined markup language like HTML defines a way to describe information in one specific class of documents only: XML lets you define your own customized markup languages for limitless different classes of document, see the question on creating your own DTD .) It can do this because it’s written in SGML, the international standard metalanguage for text markup systems.
