 6                  "multiple systems while only belonging to one. When modeling "
 7                  "this sharing relationship, one instance of LogicalDevice "
 8                  "exists to model the resource. This instance is associated with "
 9                  "the owning system via the SystemDevice association. An "
10                  "additional instance of LogicalDevice will exist for each "
11                  "system the device is shared with to represent the device in "
12                  "the context of each System it is shared with. Each of these "
13                  "instances is associated with a single instance of System via "
14                  "an instance of the SystemDevice association. This is very "
15                  "similar to the way that virtual devices are modeled. However, "
16                  "there are additional semantics associated with shared devices "
17                  "that need to be modeled, including the current access of a "
18                  "sharing system to the shared device. The SharingDependency "
19                  "association will be used to add support for modeling this "
20                  "additional semantic. It is used to associate a LogicalDevice "
