UML14 — Stereotypes on Dependency, page 43 of V 1.1 (figure 7)

Summary: There are four stereotypes shown on Dependency on page 43 of V1.1 (Figure 7).
Trace, Refinement, Binding and Usage
These are shown as peers but are in fact representative of two very different
types of partition.
My proposal is to remove Usage as a subtype of Dependency. We could than add
a new abstract type Relationship to model runtime relationships, with Associaton
and Usage as subtypes. There should be no connection between Relationship
and Dependency.

Redundant with 1227.
