Hi Peter

Not sure why you are opening up the ones we have consensus on.  

We have said multiple times that we were not proposing that we change any of the things we had already reached consensus on.  

MAYBE when we are all done and doing a language consistency run we might

 -- but lets not open up anything that has consensus until we are all done with the ones still left to do.

However, I thought it would be useful to look at it with the new UI Context definition, to help evaluate that definition and where we might use it.  My thoughts on this can be found at the Applying UI Context page in the first row, but to facilitate discussion, I reiterate them here.
