This flag is set to "true" when the user wants to delete the client and, all of the client's children
- If set to "false", an attempt to delete a client that has one more children will fail
- If set to "true", and the client and all of its children can be deleted, all clients are deleted
- If set to "true", and the InactivateIfInUseFlag is also set to true, the client and its children will be deleted if possible, otherwise they will be marked inactive. A client can be deleted if it is not in use elsewhere and all its children (if any) can be deleted. Otherwise, it must be inactivated
- If set to "true", and the InactivateIfInUseFlag is set to false, an error is returned (because at least one client cannot be deleted, per bullet 2 above)
