Summary

This corrigendum describes a number of minor changes to ITU-T Rec. Z.100 (08/2002) and to  Amendment 1 to Z.100 (10/2003) to correct and clarify some minor issues in the main body of Z.100 and in Annex B.

The changes are divided into three parts:

•            Changes to the main body (and Annex D) of Z.100 published in Z.100 (08/2002);

•            Replacement of Annex B.9;

•            Additions to Annex B.

Each of the changes to the main body (and Annex D) of Z.100 is described with a heading stating if it is a clarification, deficiency correction, extension or modification (see Appendix II/Z.100) followed by the number of the heading in Z.100 for the text to be changed. In most cases the sub‑division (Abstract grammar, Concrete grammar, Semantics or Model) in the Z.100 text is also given. The heading of each change concludes with a few descriptive words.

The changes to Annex B are to add the legacy syntax for data type definitions, which had been overlooked in the first publication of that annex in Amendment 1 to Z.100 (10/2003).
