Fred,
I am totally flummoxed here. Why do you need a 'may' and a 'should'
in the same set of requirements when 'should' can always be read
as 'may be any value, but should be x'?
Please look carefully at the definition of the 'should' keyword
before carrying this too much farther.
All the best,
.Ralph
