Hi,
if I remember it correctly, current UML documentation uses "dependency"
relationship for include/extend relations.
What is really strange is why Rational Rose even in the newest version
(2001) offers both of these stereotypes for dependency AND association
relationships... :)
What I think is that it really does not matter - you should use one type of
relationship consistently across your model / projects... :)

There are actually two bar bets here. In use case diagrams:
1. Uses/extends is the same as the newer include/extend.
2. Unidirectional association is the relationship to which these
stereotypes should apply.
I'm not trying to pin anything on Terry Quatrani -- she's my favorite
author on the UML.
Quatrani actually uses generalization with uses/extends for Rose 98, and
the unidirectional association with includes/extends for Rose 2000. Did
2000 support dependency between use cases?
Setting aside the question of what is standard according to authority,
the question is: What is right and why?
Here are three options for which relationship "goes with" include and
extend stereotypes:
1. generalization (solid line, closed arrow)
2. dependency (dashed line, open arrow)
3. unidirectional association (solid line, open arrow)
