           Summary: inheriting enveloping namespace prefixes is dangerous
           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


In Section 6, "XPath Level 1 Expression Language", of WS-Fragment it states
that "The namespace bindings are evaluated against any namespace declarations
that are in scope where the XPath appears within the SOAP message." This may
lead to unpredictable behavior because, in general, the person/software that
composed the wsf:Expression cannot know, a priori, what namespace declarations
will be in scope (i.e. they don't know what the complete SOAP envelope will
look like).

Strawman Proposal: Use something like the <prefixMapping> element from CMDBf
