Transitive

When true, an instance-gathering band includes instances of subclasses (the transitive subclass closure), not only resources typed exactly as the named class. Absent or false gathers direct instances only - the safe default, since transitive instances of rdfs.Resource would be every resource. Read by every band that enumerates a class: Instances, ResourceCount, ResourceGrid, Timeline and VersionDiff. The domain is Band rather than each of them because they share no closer superclass - the same reason metricPath carries a Band domain. An abstract base with concrete subclasses is how the ontology conventions say to model a polymorphic relationship, so a band that matched types exactly would under-report precisely the ontologies that follow the guidance; this is the opt-in that widens it.
