fn:unordered( $sourceSeq as item()* ) as item()*
Returns the items of $sourceSeq in an implementation dependent order.
Note:
Query optimizers may be able to do a better job if the order of the output sequence is not specified. For example, when retrieving prices from a purchase order, if an index exists on prices, it may be more efficient to return the prices in index order rather than in document order.
