[Modeling] Modeling an Agent Class- register your opinion

Something like Class can, and should, be used.

I don't understand the problem: even if there is any such feature,
we simply don't use it (we exclude it by means of suitable constraints
which we can associate with AgentClass).

> otherwise, we should use Classifier as the supertype?

I don't understand this idea. Don't we need new metaclasses
AgentClass and ObjectClass, which replace Class and which
are, along with AssociationClass, subclasses of Classifier
(since any agent or object class is a classifier)? 

Why don't we first attempt to define a new UML Profile (with suitable
stereotypes representing the metaclasses AgentClass and 
ObjectClass). Wouldn't this be the natural first attempt?
