You will rarely need all 17 elements at once, but the problem is that  
many non-US addresses can't be easily or accurately represented by the  
subset. (Accurate in the sense that we don't lose information as to  
the type of information we want to capture.) Also, in many cases, you  
have lower accuracy information, such as only the county.
