Hah hah, I did not know that that name was already "taken".

Marcos, we are using "subversion of control" (a joke, really, the real name is "bijection") to mean the ability to alias a contextual variable in any one of a number of scopes to an instance variable of a component:

@In @Out User user;

So that the component can get and set the value of the contextual variable by getting and setting the value of its own instance variable, and that any other stateful component will see the up to date value next time it is invoked.
