K. Davies: AUTHOR [+2]
This document specifies a method of using Extensible Markup Language (XML) to describe Label Generation Rulesets (LGRs). LGRs are algorithms used to determine whether, and under what conditions, a given identifier label is permitted, based on the code points it contains and their context. These algorithms comprise a list of permissible code points, variant code point mappings, and a set of rules that act on the code points and mappings. LGRs form part of an administrator's policies. In deploying Internationalized Domain Names (IDNs), they have also been known as IDN tables or variant tables.

Representing Label Generation Rulesets Using XML
This document describes a method of representing rules for validating identifier labels and alternate representations of those labels using Extensible Markup Language (XML). These policies, known as "Label Generation Rulesets" (LGRs), are used for the implementation of Internationalized Domain Names (IDNs), for example. The rulesets are used to implement and share that aspect of policy defining which labels and Unicode code points are permitted for registrations, which alternative code points are considered variants, and what actions may be performed on labels containing those variants.
