Christian,

I guess we just see things differently on this one.

John, Said, Donald:  do you have a preference over [2] versus [3]?  

Unless I hear otherwise by sometime today I will go with [3] for the
frozen draft.

Right. Actually, this is the point I tried to make: your example above 
illustrates a requirement on the RIF, rather than a usage of, or a need

for the RIF.

My point was simply that I prefered the scenario part of John's version

as a use case, because it tells a story of several players between whom

rules need be interchanged, like all other use cases do. And the story,

illustrated with examples of rules, tells us, albeit implicitely, what 
kind of requirements are set by this sort of usage of the RIF.

Agreed. Actually, I prefer the original scenario (the one in the MSWord

version John sent yesterday). I modified [3] to copy that version 
instead, for your convenience.

Right again. I did not mean to say that the UC should cover all the 
underlying requirements: only that a story of interchange illustrated 
what was required from the RIF as well, and made a better case for the 
use of the RIF (than the direct description and illustration of some of

the requirements).

Agreed. This is clear from the scenario as well.
