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.
Figure 34. 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:
Figure 35. 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>
