	 * TODO Right casing? What df? It seems languages are lowercase, scripts are
	 * Capitalized, territory is uppercase. I am leaving this as an exercise to
	 * the user.

	 * 1.2 Replace any deprecated subtags with their canonical values using the
	 * <alias> data in supplemental metadata. Use the first value in the
	 * replacement list, if it exists. Language tag replacements may have multiple
	 * parts, such as "sh" ➞ "sr_Latn" or mo" ➞ "ro_MD". In such a case, the
	 * original script and/or region are retained if there is one. Thus
	 * "sh_Arab_AQ" ➞ "sr_Arab_AQ", not "sr_Latn_AQ".
	 * TODO What <alias> data?
	 *
	 * 1.3 If the tag is grandfathered (see <variable id="$grandfathered"
	 * type="choice"> in the supplemental data), then return it.
	 * TODO grandfathered?
	 *
	 * 1.4 Remove the script code 'Zzzz' and the region code 'ZZ' if they occur.
	 * 1.5 Get the components of the cleaned-up source tag (languages, scripts,
	 * and regions), plus any variants and extensions.
	 * 2. Lookup. Lookup each of the following in order, and stop on the first
	 * match:
	 * 2.1 languages_scripts_regions
	 * 2.2 languages_regions
	 * 2.3 languages_scripts
	 * 2.4 languages
	 * 2.5 und_scripts
	 * 3. Return
	 * 3.1 If there is no match, either return an error value, or the match for
	 * "und" (in APIs where a valid language tag is required).
	 * 3.2 Otherwise there is a match = languagem_scriptm_regionm
	 * 3.3 Let xr = xs if xs is not empty, and xm otherwise.
	 * 3.4 Return the language tag composed of languager _ scriptr _ regionr +
	 * variants + extensions.
