Because you have to declarace ITS namespace twice and attributes have to 
be prefixed, even if elements are not (thanks to default namespace).

I prefer to think about markup design first, and about implementation 
costs afterwards. Yes, copying attribute node with a namespace change is 
not one operation, but two operations.

What is more important, is that current proposal doesn't allow to use 
attributes like its:translate on rule elements in the same way as on 
arbitrary other elements. I mean that you can't use ITS to annotate 
itself. (Other question is, whether this could be useful for something.)
