--- Comment #1 from Michael Kay <mike@saxonica.com> ---
I don't think the proposed change helps much. An implementation can still
determine that xs:decimal(.) contributes nothing to the sorting. A better fix
would be one where the test is made error-free. Perhaps 

/DataValues/(
            for $x in NegativeNumbers/*
            order by (if name(.) = 'orderData' then $x else -$x)
            return $x)

which produces different results depending on the context item used to evaluate
name(.).
