Abstract

This document describes a syntax, called a "language-range", forspecifying items in a user's list of language preferences. It alsodescribes different mechanisms for comparing and matching these tolanguage tags. Two kinds of matching mechanisms, filtering andlookup, are defined. Filtering produces a (potentially empty) set oflanguage tags, whereas lookup produces a single language tag.Possible applications include language negotiation or contentselection. This document, in combination with RFC 4646, replaces RFC3066, which replaced RFC 1766. This document specifies an Internet Best Current Practices for theInternet Community, and requests discussion and suggestions forimprovements.
