Example: Single <ditavalref> as a child of <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>
