Description Adam Retter 2015-11-06 13:11:38 UTC 
I think the second example given for array:sort in XPath F+O 3.1 may be incorrect in both the latest public and latest internal drafts.

The example given in the spec is:

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


However, if I am not mistaken then the return value should actually be:

[1, -2, 5, 8, 10, -10, 10]


That is to say that (1) the example is missing a value in the return array, and (2) that in the example the result is shown as a sequence however it should be an array.

Cheers Adam.

It was agreed that the example should be corrected, and the change has been applied.
