From the below Class Diagram it looks that the number of registrations are unlimited as the number of attendants are specified from 0 to *. However, this is actually a flaw in the UML that we cannot put constraint on objects or on the instances. Suppose that the No of Registrations is restricted to 50 or 300 depending on the type of Webinar. Draw an OCL model for the supposition we made i.e. put a constraint on the number of registrations in the webinar.
