True, but MSC is not structure-preserving: it just gloms everything
together.  What you get is only suitable for validation, not for further
work.  (This is not a criticism of MSC/MSV, which have different points
d'appui than Trang.)

The issue around identity constraints is simple: RNG doesn't have them.
