These settings define the structure of the knowledge base. Each setting can contain multiple values separated by the space character " ". Mandatory settings must be defined in at least one group per knowledge base proxy. For the initially loaded bases, these are located in the enums subdirectory. The base configurations can either specify them manually or let the application detect them manually before each task run when the key kb.structure.groups is omitted in the KB proxy definition.
