What is XML ?

Simpler SGML
XML is a meta-language.
A meta-language is a language that's used to define other languages. You can use
XML for instance to define a language like WML.
XML is a smaller version of SGML. It's easy to master and that's a major advantage
compared to SGML which is a very complex meta-language.
