Issue 7441: UML 2 Super/Interfaces (uml2-superstructure-ftf) Source: The MathWorks (Mr. Alan Moore, alan.moore(at)mathworks.co.uk) Nature: Uncategorized Issue Severity: Summary: 03-08-02 Figure 63 - firstly there ar a couple of typoes. The interface stereotype on IAlarm is missing <<, and sensor should be ISensor. More serious are the implications of the caption - "IAlarm is the required interface for any classifier implementing Isensor; conversely, Isensor is the required interface for any classifier implementing IAlarm." To me the caption sounds wrong but at the very least more explanation is needed. Firstly, does having the association to the interface imply that a usage dependency is required to ISensor from any class that implements IAlarm? If so a constraint is needed to enforce that. Secondly, isn't such a usage dependency redundant, given that its existence is implied from the presence of the association?
