           Summary: context by value and context by reference should be
                    different types
           Product: WS-Context
           Version: 1.0
          Platform: PC
        OS/Version: Windows 2000
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Schema
        AssignedTo: ws-caf@lists.oasis-open.org
        ReportedBy: peter.furniss@choreology.com
         QAContact: mark.little@arjuna.com


a context-by-value - whether passed as a header, or as returned by 
dereferencing a context-by-reference - contains elements concerned with 
whatever it is being used for - some of these are defined in ws-context, some 
will be defined in referencing specifications.

a context-by-reference, on the other hand, does not contain these elements, but 
does need to contain some others - in particular the information needed for the 
dereference. It would seem unlikely that a referencing specification would add 
elements to the reference form (possibly it should be explicitly prohibited, as 
it would complicate the implementation of the dereferencing capability)

It is confusing to represent these two different constructs as the same xml 
type with optional fields. They should be separate types, with mandatory fields 
where the required mechanisms would not work interoperably if the field were 
absent.
