XML Introduction

In 1970 IBM Introduced SGML (Standard Generalized Markup Language). SGML was developed out of the General Markup Language (GML), which was developed by IBM in the late 1960s. SGML is a semantic and structural language for text documents but is very complicated. HTML is a subset of SGML.
