Technically there isn't. It's about clarity for modellers. The above makes perfect sense to us technical people, but now we can't have a simple constraint on Event.offset, which clinical people can understand, it means we have to have some more complex UI interface in the modelling tool, so that the constraint is comprehensible to normal mortals. That;s why I am more interested in a simpler constraint (based on a computed property) and putting the expression further back in the tool structure. But that's just my view; I am interested to hear other opinions - if everyone is against computed attributes then we need to find a clean solution for this. - thomas
