Interesting proof.  Largely irrelevant, but interesting.

"Specificity" is a term of art that is exactly defined in the spec. 
You are arguing for a change in that term of art and the portion of 
the spec that defines it.  Proving that X+Y and X>Y always select 
fewer elements than X Y is not important.  What is important are the 
users and implementors.  Are users asking for the change?  How will 
they be affected by it?  Does it make the material easier or more 
difficult to use?  Is it easy to implement?  Does it break anything 
that already works reliably?

You have some good ideas, Andrew, and you are technically very adept. 
But you need to target your suggestions more carefully toward the 
material.  You haven't answered any of the questions I posed, nor 
even attempted to do so.  As far as I can see, your suggestion: 1. 
Makes the spec harder to understand. 2. Changes an existing 
implementation that is already working fine.  3. Doesn't answer any 
real user need.

As we say here in the American South: "This dog just don't hunt."
