The algorithm is based on the Lookup algorithm described in RFC 4647 section 3.4, but options specified through Unicode locale extension sequences are ignored in the lookup. Information about such subsequences is returned separately. The abstract operation returns a record with a [[locale]] field, whose value is the language tag of the selected locale, which must be an element of _availableLocales_. If the language tag of the request locale that led to the selected locale contained a Unicode locale extension sequence, then the returned record also contains an [[extension]] field whose value is the first Unicode locale extension sequence within the request locale language tag.

The BestFitMatcher abstract operation compares _requestedLocales_, which must be a List as returned by CanonicalizeLocaleList, against the locales in _availableLocales_ and determines the best available language to meet the request. The algorithm is implementation dependent, but should produce results that a typical user of the requested locales would perceive as at least as good as those produced by the LookupMatcher abstract operation.
