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. 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. 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>
