I quite frequently use association classes. An association class "hangs off of" or \
modifies a relationship between two other classes. In the diagram on the URL below, \
there is a many-to-many relationship between flights and frequentfliers. When a \
frequentflier boards a flight, she can get some arbitrary mileagecredit (determined \
in some unspecified way). The mileagecredit modifies the relationship between the \
frequentflier and the flight - it has no existence outside of that relationship.
In UML, such a class is shown as a dotted line off of the line connecting the two \
"main" associated classes.

(This is similar to bug 121725.)
P.S. I really like Umbrello. Intuitive and immediately useful.
