In the Appendix of the extended version of "Schema-based Scheduling...", CoRR cs.DB/0406016,
Q11 should be

<query11>
 { for $p in /site/people/person return
    <items>
      {$p/name}
      { for $o in /site/open_auctions/open_auction
        where $p/profile/profile_income >
                                (5000 * $o/initial)
        return
         $o/open_auction_id }
    </items> }
</query11>

Note the difference in the third-last line, which is

         { $o/open_auction_id } }
 
in the paper.

The query shown above -- correct syntax according to the XQuery specification --
was used in the experiments. That is, the fact that AnonX could not
parse it is not due to a mistake made by us.
