This interface, as well as ChangeSet, ResourceChangeNotifier, ResourceChangeListener and ResourceChangeScanner are still considered subject to change. Use the XML format change-set, as part of the ResourceType api when adding to KnowledgeBuilder, which is considered stable. KnowledgeBuilder currently ignored Added/Modified xml elements, the KnowledgeAgent will use them, when rebuilding the KnowledgeBase.
