Thanks, Vladimir. I'm not sure if we'll be able to resolve this to 
everyone's satisfaction because it comes from a "user story"[1] provided 
by someone who is no longer active in the group. Perhaps the best 
solution would be to remove some of the confusing details, but still 
have the use case be about both qualified cardinality and default 
values. I am quite sure that the details have not influenced the 
development of SHACL.
