Both HasPhysicalComponent and HasAttachedComponent are hierarchical reference (where HasPhysicalComponent is the parent of HasAttachedComponent) - should discuss if the requirement in 6.3.5 should be relaxed (in any case it should all children of HasAttachedComponent, but maybe it should be the parent reference to start with or just removed. Need to discuss in a meeting

Agreed in call to make more general (move to parent and allow subtypes)

Good to make it more general, this allows to represent slots/components not visible from the outside.
Nevertheless, figure D.3 and D.7 should be consistent.
A single change in figure D.7 replacing "HasPhysicalComponent" with "HasAttachedComponent" would do the job.

Updated figures to match (HasPhysicalComponent) also more general definition in the specification (this updated had already been made)

agreed to changes in call - closed issue
