Template Library Version 1.4

Simply put, regions are not multidimensional. They don't hold additional attributes like you've laid out here. Regions are just placeholders for content. That content can be generated in anyway you choose, but typically it is with Views.

If you need additional variables available to your master template that are not regions, use the tried and trusted $this->load->vars() method in CI.
