You're missing the point.  We don't need to verify this.  It's called 
empirical evidence.  We've already seen it with our own eyes.

Again, we have years of experience with the RFC. What you and Lofton are 
suggesting is a hypothetical premise that one can produce clear 
requirements.  This is subjective and unverifiable. My example is not 
hypothetical.  It's real and it's been demonstrated.  If one uses the same 
convention over and over, it becomes ingrained into the memory.

I think the logic you're referring to is Alex-logic.  I like to use real logic.

What we're actually doing is invoking syntax along with 
semantics.  Standards can actually do that . . .
