The IESG has approved the following document: - 'Representing Label Generation Rulesets using XML' (draft-ietf-lager-specification-13.txt) as Proposed Standard This document is the product of the Label Generation Rules Working Group. The IESG contact persons are Alexey Melnikov, Ben Campbell and Alissa Cooper. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-lager-specification/ Technical Summary 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. Review and Consensus The document was presented and discussed during at least two IETF meetings. It has the support of the WG, and there are at least three independent implementations of LGR processor with good coverage of WLE processing; the format described is already used in expressing Root Zone LGR for various writing systems. Personnel The document shepherd is Audric Schiltknecht. The responsible Area Director is Alexey Melnikov.
