[LeoWoerteler]

Query:

let $a := (copy $a := <a><b/></a> modify () return $a)
return <x>{ $a }</x>//b/ancestor::node()/name()

Expected:

x a

Result:

a

input.xml:

<a><b/><c/></a>

Query:

<A>{ doc("input.xml")/a/* }</A>/b/following-sibling::node()

Expected:

<c/>

Result: empty sequence

Possibly related (derived from test case K2-SeqIDFunc-7):

Query:

let $doc := document { <a><b/></a> } update ()
return id("id", element c { $doc/*/node() }/*)

Expected: FODC0001 (Specified node has no document node as root.)

Result: empty sequence
