Hi, Michael. 

I like most of this:

But I don't see why this added part:

> This restriction allows one copy of the 
> assume set to exist in every time step as described in 
> 17.3.1.

17.3.1 actually says,

"One copy of these contents exists for each instantiation."

Your added text omits "for each instantiation" and makes it sound as
though there is only one assume set over all instantiations.

Further, the word "one" is emphasizing the number, i.e., one and not
two. Wouldn't "a copy" be enough, and without needing to reference
17.3.1?

Thanks,
Shalom
