mm1: Harvey, I would suggest we look to our available TC processes to 
help solve this question. We have several technical preferences afoot, 
although (in line with what has started to become the obvious), I 
believe we need to evolve examples and even develop use cases here to 
understand the business and technical application and usage of the 
preferences being discussed.  Perhaps we take one case and line out 
examples where the different preferences are applied and go from there.  
We have processes in this TC why not use them.......
