Re: [xml-dev] Correct xml:lang value for Pinyin Chinese vs Simplified Chinese

True.

Standard Hànyǔ pīnyīn (汉语拼音) as used by the PRC, Singapore,
and ROC governments, and standardized as ISO 7098:1982, definitely does
have accents: one for each syllable (except for the toneless syllables),
as shown in this sentence.

Three-letter codes are never used for languages that have two-letter codes.
Chinese as a whole has the two-letter code "zh", whereas Mandarin proper
has the three-letter code "cmn".  For backward compatibility, "zh-cmn"
also designates Mandarin.

There are texts from the PRC in traditional characters.  "Zh-Hans" is
the modern standard form for simplified-character texts whether from the
PRC or Singapore or elsewhere.  "Zh-CN" usually means the same thing,
but it is a backward compatibility hack.

You're out of date here.  xml:lang definitely can specify script, though
it is not required to.

I assumed that the OP wanted to have a distinct tag for each case.
If you are going to use something ad hoc, it must take the form "x-adhoc".
