This example illustrates how to interpret a basic three-column relationship table
used
to maintain links between concept, task, and reference material.
In this scenario, a simple map establishes basic hierarchical and relationship table
links. The @collection-type and @linking attributes are then
added to modify how links are generated.
The following example illustrates how the @cascade attribute can be used
to fine tune how the values for the @platform attribute apply to topics referenced
in a DITA map.
