Interesting, I had never made a differentiation in a result-tree-fragment 
and a node set like this. I figured a result-tree-fragment could only be 
gotten on the output side and that when it would be in a variable or some 
manner that you could process it, that this was a node set. But I see the 
other part of your definition about order, which a result-tree fragment 
definitely has. I had generally equated these as the same thing just on 
different sides of the processing/output stage.

Ok so that explains why generate-id() didn't complain in the first situation.

Thanks, everyone that got the job done.
