Data Box stacks one or many Region

Region is stacked within exactly one Data Box

---

A border is drawn around each Data Box. If we want to stack multiple Metadata items in the same bordered area, we need to divide a Data Box into multiple horizontal segments. We refer to each of these a region.

In the simple case, a Data Box is dedicated to a single Metadata item and encompasses a single Region spanning the full interior.

When you want to stack multiple Metadata items, a separate horizontal Region is defined for each. For example, if you want Author printed above Date, Date would be at the bottom in Region 1 with Author in Region 2.
