Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical committees established by the
respective organization to deal with particular fields of technical activity. ISO and IEC technical committees
collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in
liaison with ISO and IEC, also take part in the work.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this Amendment may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to International Standard ISO/IEC 9541-2:1991 was prepared by Joint Technical Committee
ISO/IEC JTC 1, Information technology, Subcommittee SC 34, Document description and processing languages.

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).
