In the XQuery data model doc() do not change while a query is evaluated. So a doc() read once can in will be cached for that query. You may get what you want if you use %non-deterministic.

The built in random functions work like that.

I try to use random numbers from

Here my xpath

let $urand :=

for $i in 1 to 10 return

Which brings 10 time the same value, however, every run time a different one. 
What is wrong with this code?

Thanks in advance for your valuable input
