Description Liam R E Quin 2015-01-20 03:13:20 UTC 
I see,

The expression fn:sort((1, -2, 5, 10, -10, 10, 8), fn:abs#1)
returns (1, -2, 5, 8, 10, -10).

but I expect to get back
        (1, -2, 5, 8, 10, 10, -10)

Is the implication that duplicates are eliminated?
Comment 1 Michael Kay 2015-01-20 08:44:01 UTC 
Thanks, now fixed. 

I think the correct result is

(1, -2, 5, 8, 10, -10, 10)

The values (10, -10, 10) have equal sort keys so their order in the output should be the same as their order in the input.
