title attribute and abbreviated classnames(Was:[uf-discuss]Currency Quickpoll: Preliminary results)

[Emiliano Martinez Luque]

Hi, I've been following this discussion and I would like to add that
you might even get more characters than commas and periods inside an
ammount (which would make the regexp even more complex).. according to
this guide http://www.thefinancials.com/vortex/CurrencyFormats.html
you might have: ' used as thousands separators in switzerland (don't
know how accurate this is though). It is interesting by seeing that
guide that there are plenty of variations in how the currency
sign/currency identifier and the amount are expressed around the
world. So any optimization should take this into account.
