Hi all, In my scenario, there is metadata for the produced shapes from an ESRI system. So the ESRI system produces the SP5s always digitally.
Also in my scenario, the actual recording tool doesn't allow multi instantiation, so that would mean having to make a new class or ignoring CRMdig (and just describe the object as E73). This is no problem, I agree on further thought that it is true that not every SP5 is a D1, so indeed we can't assert it. It's just that in many use scenarios, that is likely to be the case. So probably a micro extension with 'Digital Geometric Place Expression' might be the solution to my problem or just ignoring CRMdig!
