Passive Class and Active Class are already UML classes; Agent class is the
new extension to UML Class. I believe this will make it easier for people
that are using UML for object-oriented systems to merge to systems that
contains agents and objects. I believe that current and new software
systems will contain both objects and agents.

Instances of Passive class are passive objects that holds data, but does
not initiate control (as described by UML)
Instances of Active Class are active objects that owns a thread of Control
and may initiate control activity (as described by UML).
Instances of Agent Class are agents that have all the agency features that
differentiate agent from object such as the ability to refuse requests from
other active objects, agents, or users.
