Example

The map content should be retrieved for Apache Tomcat and hidden as irrelevant for operating systems other than RedHat or SuSE.

<map>
  <title>Installing Apache Tomcat on RedHat or SuSE Linux</title>
  <topicsubject href="../controlledValues/tomcatServer.dita"/>
  <topicapply>
    <subjectref href="../controlledValues/redhatLinux.dita"/>
    <subjectref href="../controlledValues/suseLinux.dita"/>
  </topicapply>
  <!-- ... -->
</map>

Attributes

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.

@href: 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.
@processing-role: 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.
@toc: 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.
