[xquery-talk] Force a query to pause each time through a for loop?

If there is a way of doing this, then it will be entirely
processor-dependent, so you should ask on the relevant list for the product
you are using. I would have thought you ought to be looking for ways to
change that timeout value (which will also be product-dependent).

Remember that for/FLWOR is not a loop, it is a mapping expression. There is
no guarantee that the items in the input will be processed one at a time, in
sequence. XQuery 1.0 is a declarative language.
