I think that it is important to have scenario specific sections where the
finer points of the various requirements vis-à-vis the individual deployment scenario,
can be addressed in a coherent manner -
otherwise I am afraid that we loose the big picture, deployment wise.

We could under each requirement in the general requirements section
list the applicability of the requirement in the various scenarios -
like "applicable for Scenario x, Section ?.?, Scenario y etc."

As such I generally agree with the outline proposed by Pekka.

Another issue. I have some problems with SHOULD and MAY requirements.
I would much rather stick with must-only requirements, perhaps with the addition 
that a certain feature (requirement) possibly could be profited from in this and that
deployment scenario. I do not see the point in having SHOULD requirements and in general
I do not see the point in using the words MUST, SHOULD and MAY in a requirement document.

BR, Karen
