[MarkLogic Dev General] Sorting pinyin text?

[Marc Moskowitz]

I'm trying to sort transliterations of Chinese words by standard pinyin 
sorting (syllable alphabetically, then by tone, followed by the next 
syllable). Is there a collation in either English or Chinese that deals 
correctly with this? If not, is there some way of creating a 
user-defined sort order? I know that I can create a sortable form for 
each word that sorts correctly by codepoint, but I would rather do 
something more efficient if possible.
