Example: Single <ditavalref> as a child of <map>
Using a <ditavalref> element as a direct child of the <map> element is equivalent to setting global filtering conditions for the map.
The following map is equivalent to processing all the contents of the map with the
conditions in the
novice.ditaval document. If additional conditions are
provided externally (for example, as a parameter to the publishing process), those conditions take precedence.
<map> <title>Sample map</title> <ditavalref href="novice.ditaval"/> <!-- lots of content --> </map>
