Description Martin Honnen 2017-07-03 11:20:27 UTC 
https://www.w3.org/TR/xpath-functions-31/#func-exists in the "Examples" section has the following lines:

---------------------------------------------

Assuming $in is an element with no children:

               let $break := 

               return fn:exists($break)
            
The result is true().

-------------------------------------------

The right hand side in the "let $break :=" appears to be missing.
Comment 1 Michael Kay 2017-07-11 15:05:19 UTC 
The example was intended to read

let $break := <br/>
               return fn:exists($break)

(though where $in fits into that is anyone's guess)
Comment 2 Andrew Coleman 2017-07-14 10:21:54 UTC
