Returns an array containing all the members of a supplied array, except for one member which is replaced with a new value.
array:put( $array as array(*),$position as xs:integer,$member as item()*array(*)The result is an array whose size is array:size($array), in which all
members in positions other than $position are the same as the members in the corresponding position
of $array, and the member in position $position is $member.
The result is equivalent to the result of the expression
$array => array:remove($position) => array:insert-before($position, $member).
The expression array:put(["a", "b", "c"], 2, "d") returns ["a", "d", "c"].
The expression array:put(["a", "b", "c"], 2, ("d", "e")) returns ["a", ("d", "e"), "c"].
The expression array:put(["a"], 1, ["d", "e"]) returns [["d", "e"]].
A dynamic error occurs if $position is not in the range 1 to
array:size($array) inclusive.
This error will always occur if $array is empty.
