For what it's worth (I don't expect much), I share Guillaume's  
impression that historical values are not necessary for a useful  
simple-as-possible baseline version of currency.  Also, have we  
explored alternative means of capturing this information, e.g. hCal?

As is the value of "symbol," which I gather was Guillaume's point,  
and a larger concern.  Until that value is explained more  
convincingly and gains more consensus, is there any harm in moving  
forward with the smaller set of properties everyone already  
supports?  We can always add "symbol" later, right?  Or is "symbol"  
so important that a currency microformat is useless without it?  If  
so, that importance isn't yet apparent.
