A Usage dictionary entry provides more specific intended usage information than an intent entry.
The usage value can act as a kind of metadata, describing the sort of things that belong to the layer: for example, text in French, fine detail on a map, or a watermark. The usage values can also be used by the AutoState mechanism to make decisions about what layers should be on and what layers should be off.
