XQuery makes some of the XPath axes optional, they will not work in some XQuery systems.
$y/preceding::* [2 ]/string(@i) xq2xml provides an XQuery-to-XQuery transformation that replaces all references to optional axes by equivalent portable (but
probably less efficient) expressions.
$y/
(let $here := . return
reverse(root()/descendant::* [. << $here]
[not(descendant::node()[. is $here])]))
[2 ]/string(@i)
