Looks good. Since SLA is normally pronounced as the common acronym rather than the expanded term, replace "a SLA" with "an SLA". 
Thanks

    Folks,
    
    I'm working what we have to say from a model point of view (chap 2)
    based on the development since the document was firsst posted, but
    sometimes I get side-tracked.
    
    The terminology section in 3272bis says:
    
          "Service Level Objective(SLO)  A service-level objective (SLO) is a
           key element of a SLA between a provider and a customer.  SLOs are
           agreed upon as a means of measuring the performance of the Service
           Provider and are outlined as a way of avoiding disputes between
           the two parties based on misunderstanding."
    
    It was a bit hard to understand the workings of this, but after reading
    around a bit I think I get it, at least in someway the SLOs are the
    measurable atom of an SLA.
    
    But then I look at our document, and it looks like the only place where 
    SLO (the abbreviation) is used is in the terminology list.
    
    Service Level objective (without the abbreviation) is used in one other 
    place.
    
    I'd like to do the following change.
    
    In the terminology section:
    
    OLD
           Service Level Objective(SLO)  A service-level objective (SLO) is a
           key element of a SLA between a provider and a customer.  SLOs are
           agreed upon as a means of measuring the performance of the Service
           Provider and are outlined as a way of avoiding disputes between
           the two parties based on misunderstanding.
    
    NEW
           Service Level Objective -  A service level objective is a
           key element of a SLA between a provider and a customer.  Service
           level objectives are
           agreed upon as a means of measuring the performance of the Service
           Provider and are outlined as a way of avoiding disputes between
           the two parties based on misunderstanding.
    
    END
    
    And then keep the last paragraph of section 5.5 as is.
    
    Alternatively we could push the abbreviation in at all places. I can 
    write that up if you want to go that way.
    
    We could also remove service level objective altogether.
