In accordance with BCP 47, is the complete tag "cmn-Latn-pinyin"
supposed to be suitable for Mandarin in Han pinyin?  My qualm is that
the variant tag should have prefix "zh-Latn" when used for Chinese,
which suggests, contrary to other recommendations, that one should
rather use "zh-cmn-Latn-pinyin".  Do we perhaps need to add another
prefix to this and similar variants?

Richard.
