[xquery-talk] how to optimaly denormalize 1-to-many relationships with XQuery

[Michael Kay]

 >But as a side note: Do you have any insight in how expensive child, 
parent, ancestor and descendant operations are? Should one avoid those 
if possible?

implementation (not just the product you are using, but perhaps also on 
variables such as whether the input is provided in DOM form or in some 
other form).
