As the question says XQuery/XPath 3.1, if the order in the original
sequence / node list matters, generate-id made it from XSLT into newer
versions of XPath and XQuery I think so you could use grouping by
generate-id() plus sorting (as the normal XQuery group by clause doesn't
preserve the order necessarily)

for $node at $pos in $nodes
group by $id := generate-id($node)
order by $pos[1]
return $node[1]
