THe UML Views need to incorporate the casetalk_role_group, but this view needs an update to include the support for isComposite.

Composite facts are: "<Person> lives in <City> for <years> Years."
It is not elementary, and all roles need to be mandatory, and N-1 rule is ignored for at least 1 role needs to be under a UC.
This is close to a table reverbalization where all columns are not null.
It fits the old school NIAM way of working.
And sometimes this is to be found in derivable fact expressions, where the N-1 rule does not appyly.
