fn:sort

Sorts a supplied sequence, based on the value of a sort key supplied as a function, using the supplied collation. Calling the single-argument version of the function is equivalent to calling the 3-argument form with fn:default-collation() as the second argument and fn:data#1 as the third argument: that is, it sorts a sequence of items according to the typed value of the items.

sort($input as item()*, $collation as xs:string?) ➔ item()*

sort($input as item()*, $collation as xs:string?, $key as function(item()) as xs:anyAtomicType*) ➔ item()*

Arguments
	$input	item()*	The input sequence to be sorted
	$collation	xs:string?	The collation
	$key	function(item()) as xs:anyAtomicType*	The sort key
