This document describes a syntax, called a "language-range", for
specifying items in a user's list of language preferences.  It also
describes different mechanisms for comparing and matching these to
language tags.  Two kinds of matching mechanisms, filtering and
lookup, are defined.  Filtering produces a (potentially empty) set of
language tags, whereas lookup produces a single language tag.
Possible applications include language negotiation or content
selection.  This document, in combination with RFC 4646, replaces RFC
3066, which replaced RFC 1766.  This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
