DITA "Depends On" Properties
The Depends On tab provides dependency information about DITA and non-DITA content that the currently selected DITA item references.
For example, let's say the currently selected DITA content contains a cross reference to another DITA topic and a reference to an image asset. Both dependency links display within the Depends On tab list entries. Also, let's say the referenced DITA topic contains dependency links. The currently selected asset will include these links in the Depends On tab list entries, as the links correlate to the asset's hierarchical relationship structure (for example, the dependency route).
See Dependencies Overview for more details about DITA dependency linking.
