I think from what we have heard until now, it does NOT reflect a 
widespread tradition. However, in case we decide that
    text-orientation: upright;
means "but for Arabic,.., it's sidewise nevertheless", then how would 
one actually display Arabic characters upright if one wanted? Such a 
need may raise not because it's a "widespread tradition", but e.g. to 
set single characters upright when talking about single characters.

In Japanese, there is the pragmatic tradition to set longer text 
sidewise, but single letters or just a few letters upright. The later is 
called tate-chu-yoko (see in Japanese typography. 
It may be that we can say that in these cases the style mechanism for 
tate-chu-yoko (if there is one) should be used.
