Example: Multiple <ditavalref> elements in a reference to a map

Using multiple instances of the <ditavalref> element in a reference to a map is equivalent to referencing that map multiple times, with each reference nesting one of the <ditavalref> elements.

In the following example, other.ditamap is referenced by a root map. The <ditavalref> elements provide conflicting sets of filter conditions.

Map fragment

<topicref href="parent.dita">
  <topicref href="other.ditamap" format="ditamap">
    <ditavalref href="audienceA.ditaval"/>
    <ditavalref href="audienceB.ditaval"/>
    <ditavalref href="audienceC.ditaval"/>
  </topicref>
</topicref>

This markup is functionally equivalent to referencing other.ditamap three times, with each reference including a single <ditavalref> elements. The fragment could be rewritten as:

Map fragment

<topicref href="parent.dita">
  <topicref href="other.ditamap" format="ditamap">
    <ditavalref href="audienceA.ditaval"/>
  </topicref>
  <topicref href="other.ditamap" format="ditamap">
    <ditavalref href="audienceB.ditaval"/>
  </topicref>
  <topicref href="other.ditamap" format="ditamap">
    <ditavalref href="audienceC.ditaval"/>
  </topicref>
</topicref>
