http://www.w3.org/Bugs/Public/show_bug.cgi?id=11850

           Summary: MEX needs to clarify "empty" response to GetMetadata
           Product: WS-Resource Access
           Version: LC
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: MetadataExchange
        AssignedTo: public-ws-resource-access-notifications@w3.org
        ReportedBy: gilbert.pilz@oracle.com
         QAContact: public-ws-resource-access-notifications@w3.org


With respect to the GetMetadata request - given a particular set of metadata
(at a service) and a particular set of @Dialect elements and attributes (in a
request), it is possible for a GetMetadata request to effectively narrow down
the set of returned metadata sections to the empty set - i.e. there is no
metadata matching the requester's selection criteria. The spec is silent about
what happens in this case.

Proposal - add the following sentence to the end of the description of
[Body]/mex:GetMetadataResponse/mex:Metadata:

"Note, in cases where the requester, through the use of @Content and/or
mex:Dialect sub-elements in the GetMetadata request, has excluded all the
metadata maintained by the service, this element will be empty."
