The standard talks about an "instance of a Process" rather than a ProcessInstance | | Hmm... semantics? imo this is not about the intstance of a Process (Java) object but of an instance of the Process as a business object as compared to the definition. Your argument is kind of still valid than (about removing the Instance part) just in another context. Otoh, it makes it kind of clear that it is *not* a definition.

Are those only visible via the definition? It might make sense to have a method in the api that says Process.hasRunningChildProcesses() or something like that.
