+
+ cn
+ cn;lang-en
+ cn;lang-en-us
+ cn;lang-ja
+ cn;lang-ja-JP-kanji
+
+ The base language specification consists of two letters following
+ "lang-". After that, there may be additional language-specific
+ narrowings preceded by a "-". In our processing we go from the
+ specific to the general, preferring a complete subtype match, but
+ accepting a partial one. For example:
+
+ For a request for "cn;lang-en-us", we would return cn;lang-en-us
+ if present, otherwise cn;lang-en if present, otherwise cn.
+
+ Besides the language subtype, there may be other subtypes:
+
+ cn;lang-ja;binary (Unlikely!)
+ cn;lang-ja;phonetic
+
+ If not in the target, they are ignored. If they are in the target,
+ they must be in the attribute to match.
