Hi Thara,
Based on feedback from regulator folks (and also remembering that we
agreed to use the regulator framework as a later phase) let's keep your
current approach as an interim solution, but knowing that we will
eventually switch to use the regulator framework for handling multiple
requests.
In the background Thomas and I will continue to research the changes
needed in the regulator framework.
Thanks,
Kevin
