Do you think this is a case where the validation should be done at another 
place in the tool chain?

If so, even if it could be conveniently done in XSD, would you advocate 
doing it at a different place in the tool chain or in schema?

Are there circumstances where you might say, while this pattern isn't 
accurate, it's good enough?

Thanks for sharing your insight.
