Stereotype (UML) - UML-defined Stereotypes - Become

In UML, become is a keyword for a specific UML stereotype, and applies to a dependency (modeled as a dashed arrow). Become shows that the source modeling element (the arrow's tail) is transformed into the target modeling element (the arrow's head), while keeping some sort of identity, even though it may have changed values, state, or even class.

While UML 2.1 uses the «become» stereotype within the specification, it does not define it.
