>From the congo example,
LocateBookOutput is only an individual of the class "process:Output".
However, it is related with "#LocateBookOutput" by the property
"process:parameterType".
Class "#LocateBookOutput" is the union of class "#ISBN" and class
"#FailureNotification".
And "#NotifyBookOutOfStock" is an individual of class "#FailureNotification",
which is the negative effect of "LocateBook" process.

In this case, there is nothing wrong in Congo example.
