I have got three different questions: *I want to create an stereotype which extends an operation behaviour. In this sense I create an sterotype, called xx, which extends the operation metaclass.
When I want to use it I just add the lable <<xx>> before the operation name.
I wondered if it is "legal" in uml to add, as chacrteristic of the sterotype one or more attributes and operations [I mean into the profile where I define the stereotype], then this attributes and operations would be specified to the particular stereotype by using a note.
* On the other hand, if I define a stereotype called <xx> for an operation, can I have different instances of this stereotype qith different names?, How would they apper in the final model, something like <<xx: name>>operation?
* My last question is if i have an abstract stereotype can I specify a new generalization for this sterotype in a model and then use the new stereotype (children) in order to apply to an element in the model.
