RE: [ebxml-msg] question about QoS
To the team,

 

Does anyone object to renaming QOS to 
DuplicateElimination?

    question about QoS

    
I have 2 
    questions/comments about the recent talk regarding QualifyOfService and 
    DuplicationElimination.

    
 

    
1. It was said 
    that QoS with DuplicationElimination must be present in every message. Does 
    this include MSH types messages where DuplicationElimination would never be 
    true? i.e. ping/ping/StatusRequest/StatusResponse/Acknowledgements must also 
    include QoS with DuplicationElimination =false.

    
 

    
<ac>

    
The QoS element with the duplicateElimination 
    attribute set to "true" needs to be included in the message header only if 
    duplicate elimination is desired. It is quite pointless to include a QoS 
    element with duplicateElimination set to "false".

    
</ac>

    
 

    
2. Since 
    QualifyOfService only contains one attribute (DuplicationElimination) why 
    not rename the "QualifyOfService" element to "DuplicationElimination"? This 
    would also mean that question #1 above wouldn't make sense. This element 
    would only appear when "DuplicationElimination" is true. This would be more 
    in line with other elements like "AckRequested" and "SyncReply". IMO leaving 
    QualifyOfService the way it is seems inconsistent with the rest of the 
    spec.

    
 

    
<ac>

    
I agree with you that it will be more 
    consistent if we rename the QoS element the DuplicateElimination element and 
    to do away with the embedded duplicateElimination attribute.

    
</ac>
