Parameters

key

The usage key in the usage dictionary entry. Possible key values are: CreatorInfo, Language, Export, Zoom, Print, View, User, PageElement.

value

The usage information to associate with the key.

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.
