True to include containment associations up to and including the first spatial container or false to include all containment associations. This property depends on the UtilityTraceConfiguration.includeContainers property and is ignored if it's false. If no spatial containers are encountered but non-spatial containers are present for a given network element, all non-spatial containers are included in the results. This is typically used with telecommunications networks with multiple levels of containment with non-spatial objects (for example, splice points within a splice tray within a splice container). The default is false.
