Hi Judy, 

        
   

        
I wonder, if instead of changing the types for the
            specified fields, we add new fields with the preferred
            types, and deprecate use of the old fields? If KMIP 1.0
            wasn’t already an approved standard I would have no
            hesitation in supporting your proposed changes. But it is an
            approved standard, and there will be implementations using
            the current types (text strings), and so all future
            backwards-compatible implementations will have to support
            them anyway. From an implementation point of view, it might
            just be easier to keep the old field names, tags and type,
            add a new parallel set with byte string type, deprecate the
            old fields, and move forward with the new. 

      

    
    

    I think John's suggestion here is a good way to handle things -
    define new tags for the differently encoded concepts for KMIP 1.1
    and 'deprecate' the existing ones - although we will need to handle
    the concept of the varying attribute names - as given names are
    referenced by text name rather than tag id in attribute lists we
    have to have both the old and the new versions of the tag with
    separate distinct names.

    

    I also think that the "Serial" field in the Device Credential should
    be renamed to "Device Serial" and also be allocated a new tag id as
    it is separate concept that just happens to currently have the same
    name.

    

    Thanks,

    Tim.
