           Summary: [UpdateUseCases] Spec unclear whether queries are
                    "cumulative" or not
           Product: XPath / XQuery / XSLT
           Version: Working drafts
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Update Facility Use Cases
        AssignedTo: jonathan.robie@datadirect.com
        ReportedBy: jim.melton@acm.org
         QAContact: public-qt-comments@w3.org

Of the six use cases in the XQuery Update Facility Use Cases document, only one
(Use Case Parts) says anything about the relationships between the various
queries within a given use case.  Use Case parts contains the sentence "Note
that update effects are never cumulative, i.e. each update applies to the same
[initial] state of the data."

Some of the other Use Cases seem to assume that query n applies to the state of
the data that exists after query n-1 has been applied. 

A concrete decision must be made on this question, even if the decision differs
between Use Cases.  If there is a document-wide decision, then it must be
documented in some common text (e.g., the first two paragraphs of Section 1). 
If the decision varies by Use Case, then it must be documented in each of the
Use Cases independently.
