DAM1 to ISO/IEC 9541-2: Information Technology - Font Information Interchange - Part 2: Interchange Format - Amendment 1: Support for font technology advances


Introduction

This Amendment specifies an additional interchange format and slight modification to ISO/IEC 9541-2:1991. The specification is applied only when additional font properties defined by Amendment 2 and/or 3 to ISO/IEC 9541-1:1991 are employed. The properties are optional and make it possible to address advances in font technology in addition to those defined in ISO/IEC 9541-1:1991.

The additional interchange format is described by SGML (Standard Generalized Markup Language) conforming to ISO 8879:1986 and its Technical Corrigendum 2 (Annex K: Web SGML Adaptations).
