Let's assume that it can be done this way, then, we must consider agents are
special case of objects, because the semantics of class is defined as
follows. (the following is taken from Jim's email about UML's definition of
The purpose of a class is to specify a classification of objects and to
specify the features that characterize the structure and behavior of those

The question is, then, "Can agents be objects?" I doubt about it, because
the semantics of object has this features defined as a part of UML class'
semantics: (also taken from Jim's email)
"Operations of a class can be invoked on an object, given a particular set
of substitutions for the parameters of the operation." Does this give object
the freedon to refuse invocation of its operation? I think, a
characteristics of agents is that "agent can say no to operation
invocation". This is also from Jim's work.
