[Bug 8258] New: limits to expression languages and the Put operation

http://www.w3.org/Bugs/Public/show_bug.cgi?id=8258

           Summary: limits to expression languages and the Put operation
           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 last sentence of Section 7, "XPath 1.0 Expression Language", reads:

"An XPath 1.0 expression MAY evaluate to multiple nodes; because of this the
XPath 1.0 language MUST NOT be used with a "Put" or "Create" operation."

(1) There is no such thing as a WS-Frag "Create" operation.

(2) This means that no expression language that returns more than one node can
be used with the "Put" operation. This needs to be said in a generic section at
the beginning so that anyone who tries to extend the spec with their own
expression language is aware of this.
