Not quite....

As Mike Kay pointed out recently, with union "node()|@*" the nodes
will be de-duplicated and sorted into document order, but with a
sequence "@*,node()" the nodes are processed in sequential order.

So using the sequence constructor instead of union you save the
unnecessary step of sorting and de-duping.
