Book Description The Standard Generalized Markup Language (SGML) is a revolutionary innovation designed to improve the productivity and competitiveness of all computers. It greatly facilitates the sharing of data and the integration of diverse types of software, yielding a new era of efficiency and flexibility. This guide to SGML is written by the inventor of the language. In it he gives his thoughts on each clause of the widely adopted international standard, and explains every detail for the benefit of computer users. The handbook also includes the up-to-date amended full text of ISO 8879, extensively annotated, cross-referenced and indexed, along with additional tutorial and reference material. The book will be invaluable for all those involved in the development of SGML applications and the implementation of SGML systems.
