           Summary: [XQuery11UC] windowing use case Q2: wrong "at"
           Product: XPath / XQuery / XSLT
           Version: Working drafts
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XQuery 1.1 Use Cases
        AssignedTo: jonathan.robie@redhat.com
        ReportedBy: xfranc@online.fr
         QAContact: public-qt-comments@w3.org

The 'end when' condition in Q2 is incorrect and leads to typing errors:

  end at $e when $e[self::h2] 

Clearly the keyword "at" should be replaced by "next"
so that the window contains elements strictly between two h2:

  for tumbling window $w in $seq/body/* 
    start previous $s when $s[self::h2]  
    end next $e when $e[self::h2] 
  return ...
