 ### Transitivity Example
 
 - In the TypeScript reference implementation, the `communications` group contains `email` and `calendar` groups.
+  - The example client allows the user to configure the maximum depth of the depth-first graph search.
   - When listing the primitives in the `communications` group at maximum graph depth, it displays the contents of both children.
-  - So `email_thank_contributor` would appear in both `email` and `communications`.

 - Some clients might wish to only show direct children of a group (depth of 1 in the example).
