In this situation I would probably use xdmp:node-delete. That way you can
select which of the two documents to keep, and which to delete. For example the
first one might be the preferred version, so we want to delete the second one.
xdmp:node-delete(doc($uri)[2])
Be sure to delete the document-node, not the root element.
