==fn:sort==
{{Mark|Updated with Version 8.6}}: Collation argument inserted between first and second argument.
; Signatures
* <code>fn:sort($input as item()*) as item()*</code>
* <code>fn:sort($input as item()*, $collation as xs:string?) as xs:anyAtomicType*)) as item()*</code>* <code>fn:sort($input as item()*, $collation as xs:string?, $key as function(item()*) as xs:anyAtomicType*)) as item()*</code>
Returns a new sequence with sorted {{Code|$input}} items. If a sort {{Code|$key}} function is given, it will be applied on all items. The items of the resulting values will be sorted using the semantics of the {{Code|lt}} expression.
<pre class="brush:xquery">
sort(reverse(1 to 3)) (: yields 1, 2, 3 :),reverse(sort(1 to 3)) (: returns the sorted order in descending order :),sort((3, -2, 1), (), abs#1) (: yields 1, -2, 3 :),sort((1,2,3), (), function($x) { -$x }) (: yields 3, 2, 1 :),sort((1, 'a')) (: yields an error, as strings and integers cannot be compared :)
