Why are the labels for <<extend>> and <<include>> sterepotypes for use cases capitalized in Modelio? (i.e.: <<Extend>> and <<Include>>). I've never seen that before; most other modeling applications I have seen will not capitalize these.
Is there a setting where these can be changed?
(EDIT: I did notice in the meantime that Visual Paradigm seems to do this, too ... not sure if there is a rule about it, though.)
The included relationship supports the reuse of functionality in a use-case model. Extend relationships. In UML modeling, you can use an extend relationship to specify that one use case (extension) extends the behavior of another use case (base). This is the same scenario for
circle labels as well.
<<Extend>> and <<Include>> stereotypes come with internal Modelio metamodel, so I don't think there is a way to change their layout without building a new Modelio version.
