+The `ProcessRegistry` also allows use of namespaces by using a tuple as a key instead of a single value.
+If using a single value the default namespace is "predefined".
+
+Addressing entire namespaces can be done by using None as the value for process_id.

+```
+process_registry["namespace", "process_id"] = process
+process_registry["namespace", None] = processes
+
+```
+This logic can be extended to all functionalities.

 ```
+process = process_registry["namespace", "process_id"] # gets the single process named "process_id" in the namespace "namespace"
+processes = process_registry["namespace", None] # gets the entire namespace "namespace"
