Example: Defining values for @deliveryTarget

In this scenario, one department produces electronic publications (EPUB, EPUB2, EPUB3, Kindle, etc.) while another department produces traditional, print-focused output. Each department needs to exclude a certain category of content when they build documentation deliverables.

The following subject scheme map provides a set of values for the @deliveryTarget attribute that accommodates the needs of both departments.
