I might be mistaken, but I think he wants to do this:
 > let $a := (<a/>,<b/>,<c/>)
 > let $b := (xs:QName("b"), xs:QName("c"))
 > return $a/$b
.. would lead to $a being filtered by $b's QNames on the child axis, so 
the result would be <b/>,<c/> (e.g. what you would get by 
$a/element($b)). I've noticed that some people tend to understand 
Variable references in XQuery PathSteps this way.
