I think I got it Bart.
My point of view is that BSEL selectors should be different for the same BTYP.
So in your Bolt Specification you should have only one BTYP (i.e. MACH) and then three BSEL (DEF, A and B)
So choosing A will give you the STU description, and choosing B will give you the TAP description.
It is probably a bit difficult to explain it here....
But since you have opened a S.I. now, I am sure you will be in contact with some colleague of mine.
