http://www.w3.org/Bugs/Public/show_bug.cgi?id=8194

           Summary: Fragment: inconsistency w.r.t multiple nodes
           Product: WS-Resource Access
           Version: FPWD
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Fragment
        AssignedTo: public-ws-resource-access-notifications@w3.org
        ReportedBy: dug@us.ibm.com
         QAContact: public-ws-resource-access-notifications@w3.org


XPath Level 1 says:
--
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. 
---

and then it says:
--
Expressions in this language MUST NOT evaluate to more than a single node.
--

This is inconsistent and the SHOULD in the first one is asking for an
interop problem.

Proposal:

1 - s/SHOULD/MUST/ in the first sentence
2 - remove the 2nd sentence since I'm pretty sure the BNF won't allow it.
    But I'd like someone to double-check this.
