[sc34wg3] Questions on N0396: (2) one or more association memberships

[Jan Algermissen]

In section 3.8 it says:

"An association is a relationship between one or more subjects."

This implies that there can be a "relationhip between one subject".
Could you clarify what that is allowed and what meaning an association
with only one membership is supposed to convey?


I suggest to constrain the cardinality of the [roles] property of
an association item to be two or more.

If the [role playing topic] property of the association role item
would be optional, role players could missing while ensuring that
associations have at least two association roles.


What do you think?


Jan
