[Bug 8231] New: interop issue for wsf:Expressions that select multiple nodes

http://www.w3.org/Bugs/Public/show_bug.cgi?id=8231

           Summary: interop issue for wsf:Expressions that select multiple
                    nodes
           Product: WS-Resource Access
           Version: PR
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Fragment
        AssignedTo: public-ws-resource-access-notifications@w3.org
        ReportedBy: gilbert.pilz@oracle.com
         QAContact: public-ws-resource-access-notifications@w3.org


The description of the XPath Level 1 expression language says the following
about the case in which a wsf:Expression selects more than one node in the
resource:

"In the event that there is more than one node which would match the XPath, the
implementation SHOULD select or return the first node only. This allows simple
implementations to avoid the overhead of checking the remainder of the resource
document for a possible match."

The above "SHOULD" creates a number of interop problems, especially in the case
of fragment Puts.

Proposal: s/SHOULD/MUST/
