> I hit a failed test case in which I was building a list with the elements generated from a build-in function, as below,
> for $a in [
> starts-with("xyz",  null),
> starts-with("xy", "x")
> ]
> return $a
> If any of the elements is Null, it will be omitted in the returned list, e.g. the above query returns the following result:
> [ true
>  ]
> However if I explicitly add a null in the list, all the Nulls will be returned.
> the following query:
> for $a in [
> null,
> starts-with("xy",  null),
> starts-with("xy", "x")
> ]
> return $a
> will return the expected result:
> [ null
> , null
> , true
>  ]
> It applies for other similar functions which return an option value.
