Overview

External cross-reference element ‘<xref>`.

The ‘target` attribute holds a URI (http/https) pointing to an external resource. Unlike `Ref`, which uses IDREF for internal references, Xref uses anyURI for external resources.

Permitted ‘type` values:

  • Min module: ‘externalCrossReference` — reference to an external resource

  • Basic module: ‘externalCrossReference` — external reference (DC-226), `xGraphic` — graphic image associated with the concept (DC-2920)

Schema source: TBXcoreStructV03.rng ‘<define name=“xref”>`; data categories: Basic.tbxmd.
