Example: Defining values for deliveryTarget
You can use a subject scheme map to define the values for the deliveryTarget attribute. This filtering attribute, which is new in DITA 1.3, is intended for use with a set of hierarchical, controlled values.
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.
