A pointer to the resource represented by the <topicref>. See The @href attribute for detailed information on supported values and processing implications. References to DITA content cannot be below the topic level: that is, you cannot reference individual elements inside a topic. References to content other than DITA topics should use the @format attribute to identify the kind of resource being referenced.
For this element, the default value for @processing-role is "resource-only". Otherwise, the definition matches the one found in Attributes common to many map elements.
