What I meant to say is that a UML class is not an instance. This was
related to the discussion about HOOD and the problem of mapping the
notion of HOOD object to a UML element. Mapping it to a class is
controversial because the two elements are really different: a UML
class needs to be instantiated, a HOOD object is already a "runnable"
element.

Sure, but this way you may risk to model your application based on a
precise code generation strategy, possibly loosing portability and
platform-independence of models.
