The following attributes are available on this element: Universal attribute group, Link relationship attribute group (with a narrowed definition of href, given below), navtitle and query from Topicref element attributes group, outputclass, keyref, and keys. This element also uses collection-type, linking, and narrowed definitions of processing-role and toc (given below), from Attributes common to many map elements.

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.
Specifies whether a topic appears in the table of contents (TOC). If the value is not specified locally, but is specified on an ancestor, the value will cascade from the closest ancestor. On this element the default value for toc is "no". See Attributes common to many map elements for a complete definition of toc.
