mm1: I believe in past ebXML discussions, GUID and UUID terminology, 
their differences by definition, or use have been discussed. To 
Farrukh's point and in the context of the ebBP discussion, we had four 
key goals:

    * To have elements unique within a package (at a minimum)
    * To determine under what, if any circumstances, the GUID = UUID for
      key elements of the process description
    * To enable the design process where the name is important
    * Differentiate computable reference of the process description and
      elements from their understanding by users (reference Yunker on name)
    * Determine if, and if so when, canonical names are needed

I believe these goals are supported by many of the comments received 
thus far, and appear to be in concert with the ebRS and the eBA 0.83.
