IEEE floats are a classic case where many binary proposals take a 90 
degree turn  from real XML. Although you could encode IEEE floats in 
real XML, I've yet to see anybody do this in practice. What I do see 
are base-10 decimal numbers, and the round-off errors when converting 
these to base-2 IEEE floats are significant.
