// Entries for languages are lower case, for countries upper case, as
// recommended by rfc4646 (obsoletes rfc3066 (obsoletes rfc1766)).
// convertIsoNamesToLanguage() is case insensitive
//
// Sort order: Most used first.
//
// The default entry for a LangID <-> ISO mapping has to be first. For
// conversion of legacy mappings one LangID can map to multiple ISO codes, and
// one ISO code combination can map to multiple LangIDs. For compatibility with
// already existing calls it can also be a sequence as follows:

// LANGUAGE_ENGLISH,    "en", ""
// LANGUAGE_ENGLISH_US, "en", "US"

// Here, in a convertIsoNamesToLanguage() call "en-US" is converted to
// LANGUAGE_ENGLISH_US and "en" is converted to LANGUAGE_ENGLISH. A call with
// "en-ZZ" (not in table) would result in LANGUAGE_ENGLISH because the first
// entry matching the language and not having a country is returned, regardless
// of whether being sorted before or after other entries of the same language
// with some country. To obtain a _locale_ (not language only) in the order
// given, convertLocaleToLanguageWithFallback() must be called.

// If the sequence instead was

// LANGUAGE_ENGLISH_US, "en", "US"
// LANGUAGE_ENGLISH,    "en", ""

// in a convertIsoNamesToLanguage() call "en-US" is still converted to
// LANGUAGE_ENGLISH_US, but "en" is _also_ converted to LANGUAGE_ENGLISH_US
// because no country was passed and it is the first entry to match the
// language, see code. A call with "en-ZZ" (not in table) would still result in
// LANGUAGE_ENGLISH.

/* erAck: 2007-07-05T20:01+0200 TODO: The entire suite's "primary language
 * only" usage and locale fall back should be cleaned up and made consistent. I
 * strongly doubt that most callers exactly expect the behavior described.
 * Currently these primary LangIDs are used literally in AOO code:
 * LANGUAGE_ENGLISH LANGUAGE_CHINESE LANGUAGE_MALAY
 * LANGUAGE_AZERI LANGUAGE_URDU LANGUAGE_KASHMIRI
