[uf-discuss] First version of Currency proposal

[Mike Schinkel]

>> The book costs $<span class="USD">5.99</span> 

This gives me a chance to ask in a different way, why can we not assume
type=USD, amount=5.99, and symbol=$ from the following?

	The book costs <span class="currency" title="USD">$5.99</span>  

I believe you answer will be "what about unicode where we are not using
[A-Za-z0-9] and if so, I would say that is when you add a symbol. In my
example, <symbol> is the non-[A-Za-z0-9] character(s) *if* no symbol is
explicitly specified. Can you give me an example where that would not work?

Not so. Suppose there is a page with the markup (simplified):

        The book costs $<span class="USD">5.99</span>

and I have a user agent (a Firefox extension, say) which replaces the dollar
value with the value in pounds sterling. I'd get:

        The book costs $£3.50

which is clearly nonsense.

By wrapping the dollar sign in a span (or whatever) with the class "symbol",
the user agent is made aware of its presence, and can hide it when inserting
the sterling value.

Likewise for the "unit" in

        50 <span class-"unit">cents</span>
