Date tags already exist. I suppose the one for ISO date/time could be extended 
to allow just dates, unless you specifically need to differentiate dates from 
date/times. But since you appear to need times too separate from date/time, 
for completeness it may be good to support dates separately too.

When writing your specification for money quantities, please write down which 
representations you expect implementations to support in all cases, leaving 
the others as optionals. I expect you may need to name decimal fractions as 
mandatory and implementations will need to know that.
