 Are we planning to ever _recognize_ such numbers? If not, we may as well 
 recognize the dot always and the coma (or whatever) -- sometimes.
 
 Anyway, this is moot. We should be doing, what relevant RFCs/standards 
 proscribe. I thought I saw somewhere, that the dot is supposed to be 
 recognized, but I can't find a link now (everybody talks about 
 implementations, rather than specifications). We need a judgment of some 
 standards guru... Yours,
