Each property must have one base-BAR-container, which is defined by a hash # in the field BAR-definition.
SIHOT uses the base-BAR-container with its component list to determine which level is to be applied on which date. The same levels that SIHOT prescribes for the base-BAR-container are also to all other BAR-containers.
