Of course, there is a cost to this approach as well - in some environments, 
users like to look at their markup and write queries or programs based on 
what they see in the instance. With Rick's approach, most of the action is 
precisely in the things you can't see when looking at the instance 
document. On the other hand, it conveys the information you need very 
compactly if the size of the markup matters in your environment.

Again, it's best to figure out how the data will be used so you know which 
factors are important to optimize. Design is a kind of optimization, and 
you can't design until you know what you are trying to optimize.
