I am trying to perform a join operation between two large XML files

of old sql dumps into XML files. I created two databases for the files.
The query I wrote to join them is correct because it works when I limit
the join to just a few items, but it never ends if I apply it to all items:
here is the xquery:

Isn't the
where $nn
kind of meaningless? I don't think you can have an empty sequence $nn,
as you don't use `allowing empty` when you bind that variable in the
nested `for`.
No idea of course whether that changes the problem you encounter.
