112*0Sstevel@tonic-gate    language tag that looks like one of the following:

114*0Sstevel@tonic-gate    cn
115*0Sstevel@tonic-gate    cn;lang-en

118*0Sstevel@tonic-gate    cn;lang-ja-JP-kanji
119*0Sstevel@tonic-gate 
120*0Sstevel@tonic-gate    The base language specification consists of two letters following
121*0Sstevel@tonic-gate    "lang-". After that, there may be additional language-specific
122*0Sstevel@tonic-gate    narrowings preceded by a "-". In our processing we go from the
123*0Sstevel@tonic-gate    specific to the general, preferring a complete subtype match, but
124*0Sstevel@tonic-gate    accepting a partial one. For example:
125*0Sstevel@tonic-gate 
126*0Sstevel@tonic-gate    For a request for "cn;lang-en-us", we would return cn;lang-en-us
127*0Sstevel@tonic-gate    if present, otherwise cn;lang-en if present, otherwise cn.
128*0Sstevel@tonic-gate 
129*0Sstevel@tonic-gate    Besides the language subtype, there may be other subtypes:
130*0Sstevel@tonic-gate 
131*0Sstevel@tonic-gate    cn;lang-ja;binary         (Unlikely!)
132*0Sstevel@tonic-gate    cn;lang-ja;phonetic
133*0Sstevel@tonic-gate 
134*0Sstevel@tonic-gate    If not in the target, they are ignored. If they are in the target,
135*0Sstevel@tonic-gate    they must be in the attribute to match.
