Branch filtering: Single condition set for a branch

Using a single <ditavalref> element as a child of a map or map branch indicates that the map or map branch must be conditionally processed using the rules specified in the referenced DITAVAL document.

The following rules outline how the filtering conditions that are specified in DITAVAL document are applied:

<ditavalref> element as a direct child of a map

The filtering conditions are applied to the entire map.

<ditavalref> element within a map branch

The filtering conditions are used to process the entire branch, including the parent element that contains the <ditavalref> element.

<ditavalref> element within a <topicref> reference to a local map

The filtering conditions are applied to the submap.

<ditavalref> element within a <topicref> reference to peer map

The reference conditions are not applied to the peer map.
