2.2.5.3 DependencyTypes
The DependencyTypes simple type is used to represent the type of dependency that a cell storage service subrequest has on another cell storage service subrequest. The other cell storage service subrequest is identified by the DependsOn attribute of the SubRequest element. DependsOn is defined in section 2.2.4.5. Depending on the dependency type, a cell storage service subrequest is either processed or not.
