---|---|---|---|

3 | Response schema should be decided | from DMI to NCMP response schemas should be decided for single step response | Should DMI Plugins detail cm-hande IDs in response? Yes Accept or Decline |
4 | Subscription event outcome schema should be decided | from DMI to Client Apps
| We include :
