Re: [css3-writing-modes] direction vs. writing mode in markup vs. style

Hello John,

Your proposal of text-transform: chinese-numerals; makes quite bit more 
sense because it needs less intervention into the document content. 
However, if I remember the discussion of the Japanese typography experts 
on this topic that I had the chance of attending a few years ago, I 
think their conclusion was more or less: This is a slippery slope. (this 
was in the context of the committee that was responsible for JIS 4051)

There are more cases that have to be taken into account than just the 
example I gave. I think to get really good input, we have to go back to 
the Japanese typography experts. I have cc'ed the relevant list.

Regards,   Martin.
