Re: 4.4.18 RolePlayerConstraint

This seems all messed up. The cardinalities here are odd, as they can
be captured with 4.4.17.

Naming very inconsistent.

And the example invokes AssociationRoleConstraint.

It also says "that the association type //worksfor// has one role..."
An assoc type does not have roles.

I'll wait for a TMQL interpretation until that is fixed.

typo : two dots ..
typo : ... to constrain[t] ...
