UML22 — UML 2 Super / Collaboration use issues (01)

(1) All the dependencies in Figure 109 of ptc/04-10-02 are pointing in the wrong direction. Note that constraint [1] of CollaborationUse says:
"All the client elements of a roleBinding are in one classifier and all supplier elements of a roleBinding are in one collaboration..."

which implies that the supplier elements (the ends with the arrow, according to the notation subsection of Dependency) are the roles in the collaboration and the client elements are the parts that are playing specific roles of that collaboration. The figure actually shows the inverse of that.
